Correct answer: (C) 3, 4 and 5 only

Explanation

Physical environmental factors that affect communication are temperature, lighting conditions and loud noise, which are statements 3, 4 and 5.

Temperature alters comfort and concentration, shaping how smoothly an interaction proceeds.

Lighting conditions affect the visibility of non-verbal cues and the reading of a message.

Loud noise is external physical interference that distorts or blocks the signal.

A smiling face and a melodious voice are personal and vocal cues, not physical environmental factors.

Such environmental interference is studied as physical noise, a standard barrier to communication.
