UGC NET Questions (Paper – 1)

When a message has been sent,it cannot literally be erased from history,only responded to or clarified. This is why communication is described as irreversible. The effects of a hurtful or encouraging remark may continue long after it is spoken. The stem points directly to this idea,so irreversible is correct.

Option A:
Reversible would wrongly imply that communicators can undo messages completely,which is not possible once others have heard them. Apologies may reduce harm but cannot erase memory. Therefore this word contradicts the explanation.

Option B:
Irreversible means once communication occurs (spoken or expressed),it cannot be “unsent”; we can only explain,clarify or repair the impact afterward.

Option C:
Temporary suggests that communication effects vanish quickly,whereas many messages have lasting impact on relationships and attitudes.

Option D:
Optional implies that people could simply choose not to communicate,but even silence and non verbal cues convey messages,so communication is hard to avoid.
