Methods of communication

Correct answer: A. Sending private information in a public group

Explanation: Private information should be shared only with authorised people through a channel that limits access. A public group may allow many unintended members to see the information, so it creates a privacy risk. A public notice belongs on a notice board, while a greeting or open question contains no comparable confidential content.

Correct answer: A. When proof or future reference is needed

Explanation: Written communication creates a record that can be checked later, used to confirm what was agreed, or presented as evidence when appropriate. This is especially useful for instructions, decisions, dates, and responsibilities. A brief informal conversation or a facial expression does not normally require a durable written record.

Correct answer: A. मुख्य शब्दों और महत्वपूर्ण बिंदुओं को लिखना | Writing keywords and important points

Explanation: Effective note-taking means listening for the main ideas, keywords, facts, and useful supporting details, then recording them in a brief and organised form. This supports understanding, memory, and later revision. Writing every word without thinking can make a learner miss the meaning, while making no notes or drawing unrelated pictures does not preserve the lesson. Hence, A is correct.

Correct answer: A. किसी विद्यार्थी के व्यक्तिगत परिणाम पर चर्चा करते समय | While discussing a student's personal result

Explanation: A student’s personal result is private information and should be shared only with authorised people through an appropriate confidential method. A general holiday notice, school timing, and public-event announcement are normally intended for a wider audience. Confidentiality depends on the sensitivity and intended audience of the information.

Correct answer: A. तुरंत स्पष्टीकरण और चर्चा चाहिए | Immediate clarification and discussion are needed

Explanation: Oral communication is useful when people need immediate exchange, questions, and clarification, such as in a live discussion. Written communication is preferable when a permanent record, legal evidence, detailed report, or exact wording is important. The best medium depends on purpose, audience, urgency, and formality.

Correct answer: A. मित्र से परीक्षा की तैयारी पर बातचीत | Talking with a friend about exam preparation

Explanation: Informal communication is relaxed, personal, and less structured, so a conversation with a friend naturally fits it. An application to the principal, an official circular, and an employment contract have formal purposes, require suitable wording, and may need an institutional record. The relationship and purpose determine the communication style.

Correct answer: A. लिखित सूचना | Written notice

Explanation: A written notice preserves the same wording for everyone and can be read again when needed, creating a reliable record. An oral announcement may be quick but can be missed, misheard, or forgotten. Informal and gestural communication are less consistent and generally do not provide a durable official record.

Correct answer: A. What possible solutions do you suggest?

Explanation: The manager should ask for possible solutions because this moves the conversation from merely describing a problem to analysing actions that may address it. The person reporting the issue may know useful details or practical alternatives. The other questions concern unrelated personal or conversational matters and do not help the manager understand how to resolve the workplace problem.

Correct answer: A. The opportunity to strengthen the main message will be missed

Explanation: The conclusion briefly brings together the main points, reinforces the intended message, and often tells the audience what action or learning should follow. Omitting it can leave listeners unsure about the central takeaway and reduce retention. If time is short, the speaker should give a concise summary rather than remove the conclusion completely.

Correct answer: A. The sequence of instructions becomes clear and easier to follow.

Explanation: Numbering separates the instructions and gives each step a clear place in the sequence. This helps the receiver follow the process, check completed work, and avoid skipping a step. It does not remove the possible need for headings, require replies, or provide confidentiality; those depend on other features of communication.

Correct answer: A. Exchange of information and ideas

Explanation: Communication generally means the sharing or exchange of information, ideas, feelings or messages between people or groups. It may use speech, writing, gestures, images or other suitable methods, so it is not limited to writing or listening alone. The exchange also involves understanding the message, while working alone is not communication because no message is being shared with another receiver.

Correct answer: C. Written communication

Explanation: The governing concept is that communication is classified by how the message is expressed and delivered. A letter uses written words and symbols to convey information from the sender to the receiver, so it is written communication. Verbal communication depends mainly on spoken words, non-verbal communication uses gestures or expressions, and a visual signal relies primarily on images or signs; therefore, option C is correct.

Correct answer: B. Written communication

Explanation: The governing concept is that communication type depends on the form of the message. An email may be sent digitally, but its usual content is written words that the receiver reads, so it is written communication and option B is correct. It is not mainly verbal because no spoken conversation is required, and it is not physical or gestural because body movement is not the message being transmitted.

Correct answer: B. Printed written medium

Explanation: The governing concept is that a communication medium can be identified by the form in which it presents information. A newspaper distributes news, opinions, and other content as printed text, often supported by photographs and diagrams, so option B is correct. It is not primarily spoken like a conversation, and it is not merely a personal signal; its central communication form is written and printed for many readers.

Correct answer: A. Immediate feedback is available

Explanation: The governing concept is the method of communication. In face-to-face communication, the sender and receiver are present together, so spoken words, facial expressions and immediate replies can be observed. Therefore, option A is correct because it highlights instant feedback. Option B describes a possible benefit of written communication, while options C and D are incorrect: the internet is not compulsory and emotions can usually be seen through expressions and gestures.

Correct answer: B. It can be kept as a record

Explanation: The governing concept is written communication and its practical advantages. A written message can be stored, reread, shared and used as a record or reference later. Thus, option B is correct because record keeping supports accuracy and future verification. Option A merely states a limitation, not a major advantage; option C is false because written communication uses words, and option D is false because written messages may be formal or informal.

Correct answer: C. A message can be conveyed quickly

Explanation: The governing concept is verbal communication, which conveys ideas through spoken words. A speaker can deliver a message quickly and often receive an immediate response, so option C is correct. Option A is the opposite of a usual benefit, option B refers more closely to written material, and option D describes visual communication rather than spoken communication. The speed of speaking makes verbal communication useful in conversations and urgent situations.

Correct answer: B. Audio communication

Explanation: The governing concept is the communication channel used by a medium. Radio transmits information as sound, so listeners receive spoken words, music and other audio signals through hearing. Therefore, option B, audio communication, is correct. Visual communication requires images or visible symbols, written communication requires text, and touch communication uses physical contact; none is the main channel of ordinary radio.

Correct answer: C. Audio and visual

Explanation: The governing concept is audio-visual communication. Television delivers information through two coordinated channels: sound, including speech and music, and visible images, such as scenes, graphics and text. Therefore, option C is correct. It is not limited to written or printed material, signs and touch, or spoken words alone. The combination of hearing and seeing makes television an audio-visual medium.

Correct answer: A. Written and visual communication

Explanation: The governing concept is communication through displayed information. A school notice board presents written words, headings, symbols or small images in a visible place, so it combines written and visual communication. Therefore, option A is correct. It is not only verbal because no spoken exchange is required, not telephone communication, and not a private personal conversation. Readers receive the message by looking at the posted notice.

Correct answer: B. Both voice and facial expressions are available

Explanation: The governing concept is audio-visual digital communication. A video call transmits sound and a live visual image, allowing participants to hear voices and observe facial expressions, gestures and reactions. Therefore, option B is correct. Option A ignores the visual channel, option C is the opposite of interactive calling, and option D is false because a suitable device and connection are normally needed. These features make video calls richer than audio-only calls.

Correct answer: C. Written digital communication

Explanation: The governing concept is that communication is classified partly by the form in which a message is expressed and partly by the medium used. A text message contains written words, although it travels through a digital device or network. Therefore, option C is correct. It is not verbal because no spoken words are required, not physical because body movement is absent, and not merely visual because the meaning is carried by written language.

Correct answer: B. Notice

Explanation: The governing concept is formal written communication intended for a group. A school notice presents a clear announcement that can be displayed or circulated so that many students receive the same information. Therefore option B is correct. A private phone conversation reaches limited people, a hand gesture is non-verbal, and remaining silent communicates no announcement at all.

Correct answer: B. Medium

Explanation: The governing concept is the communication channel or medium: it is the method or path through which a message travels from sender to receiver. A phone, letter, email, or radio can serve as a medium. Feedback is the receiver's response, emotion is a feeling, and a barrier obstructs communication. Therefore, option B is correct.

Correct answer: C. A conversation between two friends

Explanation: Personal communication is an exchange involving a small, identified group, often with direct interaction and the possibility of immediate response. Two friends talking communicate personally with each other. A national broadcast, public poster, and large school notice are intended for a wider audience, so they are not personal communication. Thus, option C is correct.
