Answer:
d). deductive, valid, unsound
Explanation:
A deductive argument refers to an argument which is that is to be
, i.e., to provide guarantee of the truth of the conclusion provided.
When all the premises of an argument are true, then it is called a valid argument.
When an argument is either valid or invalid having at least one false premises, then it is unsound.
Thus in the context, the argument is deductive, valid and an unsound argument.
Hence the correct option is (d).
