Answer
The problem describes a ball dropped from rest that bounces multiple times. The velocity–time graph should reflect periodic upward and downward motion as the ball bounces.

Answer
We need to look for a graph that shows the velocity changing direction repeatedly, indicating the upward velocity when the ball is moving up after a bounce and downward velocity when falling.

Answer
Option 'B' is the best representation of a velocity–time graph for a dropped ball that bounces repeatedly. It shows a series of ups and downs that indicate the periodic motion of the ball.
