Truth validity and soundness – UGC NET Question

Statements A, B, C and D correctly distinguish truth from validity and define soundness. E is false because a true conclusion can result from invalid reasoning. Therefore A, B, C and D are the correct statements.

Option A:
Option A is incomplete because it omits D, the definition of soundness (validity + true premises).

Option B:
Option B is incorrect because it includes E, which is false, and it also omits D, which is true.

Option C:
Option C is incorrect because it omits A, which is true (validity does not require true premises).

Option D:
Option D is correct as it gathers all four true statements (A, B, C, D) and omits E.
