Answer:

C. valid, because it has the form of modus ponens.

Step-by-step explanation:

This argument is valid because it has the form of modus ponens. This is a rule of inference in propositional logic. This argument has two premises, P1 and P2, and a conclusion. P implies Q. P is asserted, therefore Q must follow. This argument is valid. If the first two propositions are accepted, then the conclusion follows. We cannot tell whether the propositions or the conclusion are true or false, but they are logically valid.
