Answer: A

Step-by-step explanation:

Work is defined as the inner product between the force vector and the distance traveled. Due to the energy-work theorem, the total work done is equal to the change in kinetic energy. But since there is friction, we must also take into account that frictional force. The frictional force opposes the motion of the object, and will take away energy from the object in the form of heat. Therefore, we must subtract the amount of energy done by friction from the total kinetic energy.

For your case, the answer would be A. Although, that is technically incorrect. The car does not gain energy due to friction.
