a deductive argument is invalid, but the conclusion is true.
which of the following terms best describes the argument?
cogent
sound
uncogent
unsound

Explanation:

1. Recall the definitions:

• A sound deductive argument is valid and has all true premises (so conclusion is true). Since the argument here is invalid, it can't be sound.
• Cogent and uncogent apply to inductive arguments, not deductive, so we eliminate those.
• An unsound deductive argument is either invalid or has at least one false premise (or both). Here, the argument is invalid (even with a true conclusion), so it fits the definition of unsound.

Answer:

D. Unsound
