Explanation:

Step1: Recall Newton's first - law

An object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Step2: Analyze the situation when brakes are applied

The car slows down due to the braking force. But the ball, due to inertia, wants to keep moving forward at the original speed.

Answer:

A. forward
