Correct Option: C
Explanation: In a vertical loop-the-loop, the car experiences maximum acceleration at both the top and bottom of the loop. At the top, the car is moving against gravity, so the net force is the sum of the gravitational force and the normal force, resulting in a higher acceleration. At the bottom, the car is moving with gravity, so the net force is the difference between the gravitational force and the normal force, again resulting in a higher acceleration.
