Public communication lecture – UGC NET Question

Public communication refers to a speaker addressing a relatively large audience in a formal or semi formal situation. A lecture in a big auditorium to hundreds of students fits this pattern. The speaker typically uses amplification and structured discourse.

Option A:
Intrapersonal communication is internal self talk,not a public address.

Option B:
Public communication differs from interpersonal because the audience is larger and the interaction more one sided,although occasional questions may occur. This distinction matches the lecture example well.

Option C:
Intragroup communication is communication within a small group where many members speak,which is not the case in a lecture.

Option D:
Mass communication typically involves mediated channels like TV or radio,not a live auditorium event.
