b) being accelerated.

Hello! Your answer should be D. losing mass

Explanation:

This is the only thing that makes sense, and The additional force needed to bring the car into equilibrium is if a nonzero net force is action on an object then the object is definitely the acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.
