Methods of communication

Correct answer: A. When instructions are lengthy and accurate compliance is important

Explanation: Long or important instructions can be forgotten or misunderstood when they are only spoken. The oral explanation allows questions and immediate clarification, while the written version provides a stable reference and record. A greeting or a casual message with no need for evidence normally does not require this additional written form.

Correct answer: A. Whether the recipient is correct and the communication channel is secure

Explanation: Confidentiality depends first on sending information only to the correct authorised recipient through a suitably secure channel. A wrong address or public channel can expose the information to unauthorised people. Detail and attractive formatting may improve presentation, but copying every concerned person can itself increase exposure and is not the first privacy check.

Correct answer: A. संदेश देर से पहुँच सकता है या विकृत रूप में प्राप्त हो सकता है | The message may be delayed or distorted

Explanation: A channel should match the purpose, urgency, audience, and sensitivity of a message. An unsuitable channel may delay urgent information, expose confidential content, or reduce clarity. Choosing a channel does not automatically improve the message, remove the need for understanding, or guarantee accurate feedback.

Correct answer: A. प्रस्तुति योजना | Presentation planning

Explanation: Presentation planning involves deciding what to say, how to adapt it to the audience, and how to fit it into the available time. It produces an organised and purposeful presentation. Impromptu speaking occurs without prior planning, while memorisation alone and repetition do not cover audience analysis or time management.

Correct answer: A. When you need to know how the other person has understood the message

Explanation: An open-ended question invites the person to explain an idea in their own words. This reveals what they understood, including missing details or incorrect interpretations, and therefore helps reduce misunderstanding. A yes-or-no question gives only limited confirmation. Counting people or choosing from fixed colours normally requires a short, closed response rather than an open explanation.

Correct answer: A. State the main request at the beginning, followed by the necessary details.

Explanation: A professional email should make its purpose visible early. Placing the request near the beginning lets the reader understand the required action before reading supporting background, reasons, or deadlines. The subject line should also be informative, not blank. Removing the request defeats the email’s purpose, and adding unnecessary length may reduce rather than improve clarity.

Correct answer: A. When the reasons behind their decision need to be understood

Explanation: A detailed, open response is useful when the communicator needs to understand reasons, feelings, experiences, or decision-making. It may reveal information that a yes-or-no answer cannot show. Recording attendance or confirming a known fact usually needs a closed response, and a situation requiring only a brief answer should not be made unnecessarily lengthy.

Correct answer: A. A future improvement plan

Explanation: Acknowledging a mistake accepts responsibility for the past, but a corrective plan addresses the future. The person should identify the cause, state the specific change or safeguard they will use, and explain how progress will be checked. This makes the response more trustworthy and useful. Anger, privacy violation, and picture selection neither prevent recurrence nor show improvement.

Correct answer: B. All tasks may appear equally important

Explanation: Deadlines and assigned people clarify who will do what and by when, but they do not always show which task should receive attention first. Without priorities, team members may treat urgent, dependent, and less important tasks as equal, causing delays or poor sequencing. The language, confidentiality, and receiver are not directly affected, so B is correct.

Correct answer: B. Channel and audience-reach selection

Explanation: Communication succeeds only when an accurate message reaches the people who need it through a suitable channel. Posting a notice on the wrong platform can prevent the intended audience from seeing it, even if its wording and facts are correct. This is a failure to choose the proper medium and audience reach, not a failure of language, timing, or organisation.

Correct answer: B. Private information may reach unintended recipients

Explanation: Reply All sends the response to every address included in the original message, not only to the person who needs the information. If the reply contains private details, those details may be disclosed to people without a legitimate need or permission. This creates a confidentiality and privacy risk. It does not automatically change the message length, subject line, or language, so B is correct.

Correct answer: B. List each group’s tasks under a separate heading

Explanation: Separate headings make a long or shared message easier to scan and understand. Each group can quickly find its own responsibility, deadline, or instruction without confusing it with another group’s work. Option A is unsuitable because an unclear sentence can mix responsibilities. Options C and D do not communicate the actual actions required, so they cannot guide the groups effectively.

Correct answer: A. The audience may remember the conclusion without understanding the reason.

Explanation: Complex ideas are easier to understand when the speaker first explains the background, terms, evidence, and reasoning, and then reaches the conclusion. Giving only the conclusion may produce memorisation without genuine understanding and may leave listeners unable to apply the idea. It does not remove questions or affect confidentiality.

Correct answer: A. Ambiguity caused by the lack of a specific deadline

Explanation: The word “soon” is subjective and can mean different dates to different people. The first problem is therefore unclear wording about the deadline. The leader should specify an exact date, time, and time zone if necessary. Feedback delay would concern a missing response, while technical noise and non-verbal cues are not indicated by this written message.

Correct answer: A. Verbal and visual communication

Explanation: The teacher’s spoken explanation uses verbal communication because words are delivered through speech. The diagram uses visual communication because information is represented through sight. Since both channels operate together, the combination is verbal and visual communication. Written-only, non-verbal-only, and postal communication do not describe the complete situation, so option A is correct.

Correct answer: B. Written email

Explanation: A written email is appropriate for an official instruction because it records the sender, recipient, wording, and time of the communication. The employee can review the instruction later, and the organisation can retain the message as evidence. A conversation, gesture, or informal call may communicate quickly but does not provide the same reliable written record. Option B is correct.

Correct answer: C. Audio-visual communication

Explanation: A video conference carries spoken voices through the audio channel and facial expressions through the visual channel. Because sound and images are received together, it is audio-visual communication. It is not verbal-only or visual-only, since each of those leaves out one important channel, and it is not written communication. Therefore, option C is correct.

Correct answer: A. Phone call

Explanation: A phone call is most effective when help is needed immediately because it transmits the request rapidly and allows two-way interaction. The receiver can ask questions, confirm the situation, and guide the caller while help is arranged. A postal letter, magazine, or wall poster cannot normally provide such immediate personal feedback. Therefore, option A is correct.

Correct answer: B. Written notice and notice board

Explanation: A written notice displayed on a notice board communicates the rules consistently to a large audience and creates a lasting reference that students can read again. It is clearer and more formal than a rumour or casual conversation, while a private gesture reaches too few people and cannot record the rules. Hence, option B best meets both the clarity and permanence requirements.

Correct answer: B. When a formal permanent record is needed

Explanation: The governing concept is choosing a communication medium according to the purpose. A letter is appropriate when the sender needs a formal, detailed, and lasting written record that can be checked later. A phone call is usually better when an immediate reply or urgent assistance is required, while facial expressions require a face-to-face or visual medium. Therefore, option B is correct.

Correct answer: C. Listeners may fail to understand parts of the message

Explanation: The governing concept is effective verbal communication, which requires a suitable speaking pace, clear pronunciation, and pauses. If a speaker talks too rapidly, listeners may not process each word, take notes, or identify the main ideas in time. Speed does not automatically improve effectiveness or create a written record. Therefore, option C correctly describes the likely communication problem.

Correct answer: D. Non-verbal feedback

Explanation: The governing concept is non-verbal feedback: people can communicate attitudes and reactions through behaviour without speaking. Repeatedly looking at the clock may suggest impatience, lack of time, or a wish to end the interaction, although context should also be considered. It is not a written notice or an audio message. Therefore, option D is the best answer.

Correct answer: A. The message is understood more quickly and clearly

Explanation: The governing concept is visual communication, in which pictures, symbols, and written words work together to convey meaning. A suitable picture can show an action, danger, or direction quickly and can support readers who may not understand a long sentence easily. It does not remove the record, make the instruction informal, or eliminate feedback. Thus, option A is correct.

Correct answer: B. Language barrier

Explanation: The governing concept is communication barriers. When the sender and receiver do not share or understand the language used, the receiver may interpret the words incorrectly or fail to understand them at all. This is specifically a language barrier, not a physical barrier, visual aid, or positive feedback. Using simple, familiar language or translation can reduce the problem. Therefore, option B is correct.

Correct answer: C. The listener cannot hear the voice properly

Explanation: The governing concept is the physical barrier in verbal communication. External noise competes with the speaker’s voice and can cover or distort spoken words, so the listener may miss important information even when the speaker is using correct language. Noise does not create a written record, improve facial expressions, or turn speech into visual communication. Therefore, option C is correct.
