If an original conditional statement is represented by p → q, which represents the contrapositive?

q → p

~q → ~p

p → q

~p → ~q

A conditional statement has two parts, the hypothesis and the conclusion. In p and q notation, the hypothesis is always the p and the q is the conclusion. In a contrapositive statement, the statement would go, "if not q, then not p". Therefore, the answer to this item is the second choice.
