c hit the front wall
d stay where it is

Explanation:

According to Newton's first - law (law of inertia), an object at rest tends to stay at rest. When the wagon is suddenly pulled forward, the ball initially at rest in the wagon wants to remain at rest relative to the ground. So, relative to the moving wagon, it will hit the back wall as the wagon moves forward.

Answer:

B. hit the back wall
