According to the principle of logic, an implication and it's contrapositive must be
F is actually equivalent to contrapositive of F. So both have the same value. Option A
If you take the converse of F, and apply contraposition to it, you'll find that converse of F is actually equivalent to the inverse of F. They have the same value too.
In other words: 1 is equivalent to 4; 2 is equivalent to 3.
