non-verbal

Correct answer: A. Professional impression and attention

Explanation: A virtual meeting includes visual as well as spoken communication. A messy background can distract viewers, draw attention away from the speaker, and create a less professional impression. It does not calculate dates, change a file’s size, or determine the correctness of an answer. A tidy or suitable background supports concentration.

Correct answer: A. The student lacks confidence

Explanation: Voice volume and posture influence how a speaker is perceived. A very low voice may be difficult to hear, while a lowered or closed posture can suggest nervousness or low confidence. These signals do not prove what the student feels, but they may create that impression. Clear volume and balanced posture usually support better delivery.

Correct answer: A. The listener may become confused

Explanation: Spoken words are verbal signals and facial expressions are non-verbal signals. If they communicate different attitudes, the listener may be unsure which signal to believe and may question the speaker’s sincerity. Matching signals usually improves clarity. A mismatch does not automatically strengthen the message, remove feedback, or change the mode into written communication.

Correct answer: A. अमौखिक संचार | Non-verbal communication

Explanation: Facial expressions, gestures, posture, and eye contact convey meaning without relying on spoken or written words, so they are forms of non-verbal communication. Verbal communication uses words, written communication uses text, and telephonic communication describes a channel that may include spoken words but does not specifically name these visual cues.

Correct answer: D. Non-verbal communication

Explanation: The governing concept is that non-verbal communication conveys meaning without relying on spoken or written words. Facial expressions such as smiling, frowning, or looking surprised communicate emotions and attitudes through the face, so option D is correct. Written and printed communication use text, while verbal communication normally uses spoken language; none of those best describes facial expressions.

Correct answer: C. Non-verbal signal

Explanation: The governing concept is that non-verbal communication expresses meaning through actions, gestures, facial expressions, or posture instead of words. Waving a hand can greet another person without any spoken or written message, so option C is correct. A written message and a formal letter require text, while a spoken message requires words said aloud; the hand movement itself is the signal.

Correct answer: D. Body gestures

Explanation: The governing concept is non-verbal communication, in which meaning is conveyed without relying mainly on spoken or written words. Body gestures, posture, facial expressions and eye contact can communicate feelings or intentions, so option D is correct. Writing an email and reading a letter involve written language, while speaking on a phone is verbal communication. These distinctions identify the communication channel used.

Correct answer: A. Non-verbal communication

Explanation: The governing concept is body language as a form of non-verbal communication. Eye contact can show attention, confidence, interest or emotion without itself using words, so option A is correct. Verbal communication depends primarily on spoken words, while written and printed communication depend on visible text. Eye contact may accompany speech, but its communication function remains non-verbal.

Correct answer: D. Non-verbal communication

Explanation: The governing concept is non-verbal communication: meaning is conveyed through facial expressions, gestures, posture, eye contact, signs, or other cues rather than spoken or written words. Thus option D is correct. Written and verbal communication depend on words, while email is a digital channel that normally carries written words; it is not, by itself, a wordless method.

Correct answer: A. Verbal communication

Explanation: The governing concept is verbal communication, in which a speaker uses spoken language to convey information, ideas, or feelings to listeners. A speech is delivered aloud, so option A is correct. A written script may support the speaker, but the act of giving the speech is not classified as written or printed communication. Visual aids can accompany it, yet they are not its primary method.

Correct answer: D. Friendliness or happiness

Explanation: The governing concept is non-verbal communication, especially facial expression. A smile is produced without spoken or written language and commonly signals friendliness, happiness, welcome, or positive feeling. Therefore option D is correct. A written order, a report, and a phone message are forms of verbal or written content, not meanings normally conveyed by the facial expression of smiling.

Correct answer: C. An upright and relaxed posture

Explanation: Posture communicates attitudes without spoken words. An upright but relaxed posture generally suggests attention, openness, and confidence, making interaction easier. Turning away, repeatedly looking elsewhere, or hiding the face can signal disinterest, discomfort, or unwillingness to engage. The appropriate posture should not be rigid; it should be natural and respectful. Therefore, option C is correct.

Correct answer: C. Digital written communication

Explanation: An emoji is a visual sign added to a digital message to express emotion, tone, or reaction. It can make a written chat feel happier, sadder, or more encouraging, so option C is the best answer. The message is written digitally, although the emoji adds non-verbal meaning. A speech and a radio broadcast depend mainly on sound, while a parcel is an object rather than a communication type.

Correct answer: D. Non-verbal communication

Explanation: Non-verbal communication conveys meaning without relying on spoken or written words. Facial expressions such as smiling, frowning, or showing surprise communicate emotions and attitudes through the face. They may support spoken language, but they remain non-verbal signals in their own right. Therefore option D is correct; writing, speech, and telecommunication describe different channels.

Correct answer: C. Happiness or friendliness

Explanation: A smile is a non-verbal communication cue whose usual social meaning is happiness, warmth, welcome, or friendliness. The word “generally” matters because context can sometimes make a smile nervous, polite, or ironic; however, none of those possibilities makes anger, fear, or no message the best general answer. Therefore option C is correct.

Correct answer: A. Verbal communication

Explanation: When a teacher explains a lesson by speaking, information is transmitted through words and voice. This is verbal communication, and in a classroom it is usually a formal, face-to-face form of communication. The teacher may also use writing, gestures, or visual aids, but the action described is explaining through speech. Therefore option A is the best answer.

Correct answer: C. Non-verbal communication

Explanation: Eye contact communicates attention, confidence, interest, respect, or sometimes discomfort without using written or spoken words. It is therefore a form of non-verbal communication and an important part of body language. Context affects its precise meaning, but it does not turn eye contact into written, printed, or purely audio communication. Hence option C is correct.

Correct answer: B. Verbal communication

Explanation: The governing concept is the use of vocal features in spoken communication. Variation in pitch, loudness, speed, and stress can show emotion, emphasis, politeness, or urgency and can change how a spoken sentence is understood. Therefore, option B is correct. Visual, printed, and picture communication may use design features, but they do not depend on the speaker’s changing voice tone.

Correct answer: C. Body language

Explanation: The governing concept is non-verbal communication, in which meaning is conveyed without relying on spoken or written words. Posture is the way a person holds or positions the body, and it can suggest confidence, attention, discomfort, or disinterest. Therefore, option C, body language, is correct. Written, audio, and printed communication depend on recorded or heard messages rather than body position.

Correct answer: D. Giving information to a visually impaired person

Explanation: The governing concept is tactile, or touch-based, non-verbal communication. When visual information cannot be received easily, raised dots, textures, or agreed touch signals can convey meaning. Braille is a clear example of tactile information for people who are blind or visually impaired. Therefore, option D is correct. Reading an ordinary book, listening to radio, and writing email do not by themselves require touch signals to communicate their main message.

Correct answer: C. Hand signs and facial expressions

Explanation: The governing concept is non-verbal communication, in which meaning is conveyed without relying on spoken words. Sign language uses systematic hand shapes, movements, positions, and facial expressions to communicate information. Option C is correct because it describes the main visible elements of signing. Written words, sound alone, and printed pictures may communicate in other situations, but they do not define sign language itself.

Correct answer: D. Non-verbal communication

Explanation: The governing concept is non-verbal communication, which communicates feelings, attitudes, or intentions without using spoken sentences. Facial expressions such as a smile, frown, or raised eyebrows can add meaning to a situation even when a person says nothing. Option D is correct. Written, oral, and audio communication depend respectively on written symbols or sound, whereas facial expressions are visible body-language cues.

Correct answer: A. Non-verbal communication

Explanation: The governing concept is that communication can occur through gestures and physical actions without spoken or written words. A handshake may convey greeting, respect, welcome, friendship, or agreement through touch and social convention. Thus, option A is correct because it is non-verbal communication. Written communication requires text, digital communication requires an electronic channel, and radio communication uses transmitted sound, so the other options do not describe the handshake itself.

Correct answer: A. Non-verbal communication

Explanation: The governing concept is non-verbal communication, in which meaning is conveyed without spoken or written language. A person who nods can communicate agreement, acceptance, or understanding through a visible head movement. Therefore, option A is correct. Written communication needs words in a written form, radio communication depends on broadcast sound, and email communication uses a digital written message, so none of those describes the nod itself.

Correct answer: C. Non-verbal communication

Explanation: The governing concept is body language as a part of non-verbal communication. Posture, such as standing upright, crossing the arms, or bending the shoulders, can suggest confidence, openness, discomfort, or hesitation without using spoken or written words. Therefore, option C is correct. Email and print communication depend on written text, while telephone communication mainly uses voice, so they do not identify body posture itself.
