Solution

The correct option is A Change in speed
Force can produce any of the following effects:

Change the state of motion of an object.

Change the direction of a moving object.

Change the shape and size of an object.

In the given case, when a driver applies brakes on a moving car, it will change the speed of the car thereby slowing it down. However, it will not change the car's shape, mass, and direction.
