Selecting appropriate communication channels – UGC NET Question

Statements A, B and D are correct, while C is the only wrong statement. A is true because formal policy changes require an official record and clarity that written notices provide. B is true since informal reminders about everyday matters can suitably be sent through instant messaging groups. D is true as richer channels are generally preferred for complex or ambiguous messages, while leaner channels can suffice for simple information. C is false because giving sensitive feedback in a public mass e-mail violates privacy and professional courtesy; such matters should be handled privately.

Option A:
Option A correctly identifies C only as the wrong statement. It recognises that formal, informal and rich channels each have their place, but sensitive feedback must not be delivered publicly. By excluding A, B and D from the wrong set, this option accurately selects the statement that misguides channel choice. Therefore C only is the correct answer.

Option B:
Option B groups A and C as wrong and thereby mislabels A, which appropriately recommends official written notices for policy changes. Treating A as wrong contradicts accepted administrative practice. Hence A and C only cannot be accepted.

Option C:
Option C combines C and D as wrong, even though D correctly states a key principle of channel selection. Including D among wrong statements undermines a fundamental idea in media richness theory. Therefore C and D only is an invalid option.

Option D:
Option D lists A, C and D as wrong and thus incorrectly treats A and D as false. Since both of these statements align with standard recommendations for institutional communication, this combination exaggerates the number of wrong statements. Consequently A, C and D only cannot be chosen.
