Statement assumption core ideas – UGC NET Question

A is correct because assumptions are taken as underlying ideas that the argument depends on. C is true as implicit ideas that make the statement meaningful count as assumptions. D is also correct because many NET items ask whether a given assumption is implicit in the statement. B is false since assumptions are not always explicitly stated, and E is false because some proposed assumptions may be illogical or extreme. Therefore, A, C and D only are correct.

Option A:
Option A correctly gathers the three statements that reflect how assumptions work in reasoning questions and discards B and E, which misrepresent explicitness and logical acceptability. It fits the exam pattern for statement–assumption items.

Option B:
Option B wrongly includes B, which insists on explicit stating, contrary to the very idea of an assumption being implicit. Hence it cannot be correct even though it includes A and C.

Option C:
Option C includes B and thus inherits the same error about explicitness, even though it also includes C and D, both of which are true. Mixing a false statement with true ones invalidates the option.

Option D:
Option D is incorrect because it includes E, which incorrectly suggests all assumptions offered are sound, and omits C, ignoring the role of implicit background beliefs.
