Answer:

C

Explanation:

First of all KE is an energy that measures velocity, so the object has to be moving.

That lets out both A and D.  When the car is at it's highest it must stop so it can change direction. In both A and D, the car is getting ready to fall.  

B has some KE because the car is moving but it is not the answer.

The answer is C.  The car has turned all the PE it had at point A into KE

The answer then is C

Question B

The car is at a minimum when it is not moving. The velocity is 0. So that's at A and D. Both places have a velocity of 0.
