UGC NET Questions (Paper – 1)

Statements A, B and C are correct, whereas D is incorrect. A is true because face-to-face interaction includes verbal content, voice tone and body language, and allows rapid feedback. B is true since written notices typically provide only text and do not convey vocal or facial cues, making them lean. C is true as rich channels help clarify complex or ambiguous issues by permitting questions and elaboration. D is false because emotional issues are often better handled through richer channels that allow empathy and nuance, not lean channels alone.

Option A:
Option A is incorrect because it lists A and B only and omits C, which highlights the particular usefulness of rich channels for complex messages. Without C, the description of richness is partial. Therefore A and B only cannot be the correct answer.

Option B:
Option B is incorrect because it groups B and C only and leaves out A, ignoring the classic example of face-to-face communication as a rich channel. Since A is also correct, B and C only is incomplete.

Option C:
Option C is correct because it brings together A, B and C, presenting a coherent view of rich versus lean channels and their appropriate use. It excludes D, which overstates the value of lean channels for emotional content. As it includes all and only the correct statements, this option is the right one.

Option D:
Option D is incorrect because it treats all four statements as correct, including D. D conflicts with communication practice by claiming that lean channels are always superior for emotional matters. Mixing this false claim with accurate statements makes the option invalid.
