A batsman hits a cricket ball which then rolls on a level ground. After covering a short distance, the ball comes to rest. The ball slows to a stop because (a) the batsman did not hit the ball hard enough, (b) velocity is proportional to the force exerted on the ball, (c ) there is a force on the ball opposing the motion ,(d) there is no unbalanced forcr on the ball, so the ball would want to come to rest.

Explanation

To solve the question about why a cricket ball comes to rest after being hit by a batsman, we will analyze each option provided and determine the correct reasoning.

### Step-by-Step Solution:

1. **Understanding the Scenario**:
- A batsman hits a cricket ball, which then rolls on a level ground. After covering a short distance, the ball comes to rest.

2. **Analyzing Option (a)**:
- **Statement**: The batsman did not hit the ball hard enough.
- **Evaluation**: This statement is false. If the batsman had hit the ball harder, it would have increased the ball's velocity, but that does not explain why the ball eventually stops.

3. **Analyzing Option (b)**:
- **Statement**: Velocity is proportional to the force exerted on the ball.
- **Evaluation**: While this statement is true, it does not directly explain why the ball stops. It only states a relationship between force and velocity, not the reason for the ball coming to rest.

4. **Analyzing Option (c)**:
- **Statement**: There is a force on the ball opposing the motion.
- **Evaluation**: This statement is correct. When the ball rolls on the ground, it experiences two main forces opposing its motion: air resistance and friction from the ground. These forces slow down the ball and eventually bring it to a stop.

5. **Analyzing Option (d)**:
- **Statement**: There is no unbalanced force on the ball, so the ball would want to come to rest.
- **Evaluation**: This statement is misleading. The ball does experience unbalanced forces (air resistance and friction), which are responsible for its deceleration and eventual stop.

6. **Conclusion**:
- The correct answer is option (c): "There is a force on the ball opposing the motion." This explains why the ball slows down and comes to rest.

### Final Answer:
The ball slows to a stop because (c) there is a force on the ball opposing the motion.
