Classroom group communication networks – UGC NET Question

Statements A, B and D are correct, while C is the only wrong statement. A is true because in a wheel network information typically passes through a central figure who links the others. B is true as a chain network resembles a line where each member is connected to neighbours in sequence. D is true since in an all-channel network every member can communicate with every other, allowing high participation. C is false because a circle network connects members to their immediate neighbours, not solely to the teacher.

Option A:
Option A is incorrect because it lists A and C as wrong statements, even though A correctly defines a wheel network. Including A among wrong statements misrepresents established network types. Therefore this option cannot be accepted.

Option B:
Option B is incorrect because it groups B and C as wrong. B is a correct description of a chain network, so treating it as wrong contradicts network theory. Although C is wrong, pairing it with B makes this combination invalid.

Option C:
Option C is incorrect because it identifies C and D as wrong statements. D accurately describes an all-channel network where all members can interact freely. By labelling D as wrong, the option conflicts with the basic definition of this network type.

Option D:
Option D is correct because it isolates C only as the wrong statement while acknowledging the accuracy of A, B and D. It reflects the fact that a circle network links members horizontally to one another, not just vertically to the teacher. Thus this option matches the pattern of correct and incorrect statements.
