Is a hypothetical proposition equivalent to its converse? To its contrapositive?

A) It is equivalent to its converse, but not to its contrapositive.
B) It is equivalent to its contrapositive, but not to its converse.
C) It is equivalent to both.
D) It is equivalent to neither.
E) It depends on the subject matter of the proposition.

A hypothetical proposition is a conditional statement of the form "if p, then q". The converse of this statement would be "if q, then p", and it is not equivalent to the original statement. However, the contrapositive of the original statement would be "if not q, then not p", and this statement is equivalent. Therefore, option B is the correct answer.
