Explanation:

In logic (a subfield related to Philosophy in Arts or sometimes Mathematics), a valid argument is defined as one where if the premises are true, the conclusion must be true (i.e., the conclusion necessarily follows from the premises). Option B describes an invalid or non - valid argument situation. So the correct option is A.

Answer:

A. When the conclusion necessarily follows from the given set of premises.
