Answer
Brief Explanations:
In logic, a conditional statement (p\rightarrow q) has a contrapositive (\neg q\rightarrow\neg p), and they are logically equivalent. The inverse of (p\rightarrow q) is (\neg p\rightarrow\neg q), the converse is (q\rightarrow p). The inverse, converse are not logically equivalent to the conditional, and they are not equivalent to the contrapositive either.
Answer:
A. Conditional and contrapositive
