Nature of communication noise – UGC NET Question

Statements A and B are correct, whereas C and D are wrong and therefore form the correct combination of wrong statements. A is true because physical noise includes sounds such as traffic or construction that interfere with hearing a message. B is true since internal factors like prejudice and bias may distort how messages are interpreted and thus act as psychological noise. C is false because noise can arise at any point in the communication process, including at the receiver’s side. D is false because rigid rules and hierarchy may obstruct free flow of information and thus create a kind of organisational noise.

Option A:
Option A is incorrect because it treats C only as the wrong statement and overlooks D. While C is indeed wrong, D also misrepresents the possibility that organisational structure can interfere with communication. Leaving D out means this option does not capture all the wrong statements.

Option B:
Option B is incorrect because it selects D only as wrong and ignores C. Although D is a false statement, C is equally incorrect in claiming that noise never originates from the receiver. Since the question asks for all wrong statements, an option that includes only D cannot be accepted.

Option C:
Option C is correct because it groups C and D, the two statements that misrepresent the nature and sources of noise. It recognises that both the sender and receiver, as well as organisational structures, can contribute to noise in communication. By excluding A and B, which are accurate descriptions of physical and psychological noise, this option exactly matches the set of wrong statements.

Option D:
Option D is incorrect because it includes A, C and D as wrong statements. A is actually a correct statement defining physical noise as external sound interference. Including A among wrong statements makes this combination overinclusive and inconsistent with communication theory.
