Assertion: A glass ball is dropped on concrete floor can easily get broken compared if it is dropped on wooden floor.
Reason: On concerte floor glass ball will take less time to come to rest.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reson are true but reason is not the correct explanation of assertion.
C. if assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that a glass ball dropped on a concrete floor is more likely to break compared to when it is dropped on a wooden floor.
- This is true because concrete is a much harder surface than wood, which means that when the glass ball impacts the concrete, the force exerted on the ball is significantly greater.

**Hint**: Consider the properties of the surfaces involved—hardness and energy absorption.

2. **Understanding the Reason**:
- The reason given is that the glass ball will take less time to come to rest on a concrete floor.
- When the ball hits the concrete, it experiences a rapid change in momentum due to the high stiffness of the surface, which results in a quick deceleration. This rapid change in momentum can lead to the ball breaking.

**Hint**: Think about how momentum change relates to the time taken to stop and how it affects structural integrity.

3. **Connecting Assertion and Reason**:
- The assertion is true, and the reason provided is also true. The reason correctly explains why the assertion is true: the quick change in momentum on a hard surface like concrete leads to a higher likelihood of breaking the glass ball.

**Hint**: Analyze if the reason logically supports the assertion.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.

### Final Answer:
The correct option is that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
