Characteristics of Shannon Weaver model – UGC NET Question

Statements A, B and D are correct, while C is the only wrong statement. A is true because the Shannon–Weaver model identifies source, transmitter, channel, receiver and noise as key elements. B is true since it emerged from engineering efforts to improve telephone and telegraph systems. D is true as the model conceptualises communication chiefly as information transfer through a channel subject to noise. C is false because the basic Shannon–Weaver model does not explicitly incorporate feedback; feedback was highlighted more clearly in later models.

Option A:
Option A correctly identifies C only as the wrong statement. It acknowledges the historical and structural aspects of the model while noting that feedback is not a central part of the original formulation. By leaving A, B and D outside the wrong set as correct, this option accurately answers the question. Therefore C only is the correct answer.

Option B:
Option B combines A and C as wrong statements and therefore misclassifies A, which correctly describes central elements of the model. Treating A as wrong conflicts with standard textbook explanations of Shannon–Weaver. As a result, A and C only is not a valid option.

Option C:
Option C groups C and D as wrong, even though D is a correct statement about the transmission view of communication. Including D among wrong statements contradicts how the model is typically interpreted. Hence C and D only cannot be accepted.

Option D:
Option D lists A, C and D as wrong and thereby incorrectly labels both A and D as false. Since these statements accurately describe the model’s elements and its information-transmission focus, this option substantially misrepresents the theory. Consequently A, C and D only is not the correct answer.
