A4 only

B1 and 2 only ✓ Correct

C2 and 3 only

D2 and 4 only

Correct answer: (B) 1 and 2 only

Explanation

Only statements 1 and 2 are true.

Validity is a property of arguments, so it never attaches to a lone proposition.

A single proposition can, however, bear truth or falsity.

Since validity does not apply to propositions at all, they are neither valid nor invalid.

Truth and falsity belong to propositions, validity to arguments alone.
