C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Improvement cutting is an important practice in forest management." This means that improvement cutting is recognized as a beneficial method used to manage forests effectively.

2. **Understanding the Reason**: The reason provided is "It provides space for growing new healthy trees." This suggests that one of the benefits of improvement cutting is that it creates room for healthier trees to grow.

3. **Analyzing Improvement Cutting**: Improvement cutting involves selectively removing certain trees from a forest. This can include removing trees that are diseased, defective, or of poor quality. The goal is to enhance the overall health and quality of the forest.

4. **Connecting Assertion and Reason**: Since improvement cutting does indeed create space for new, healthy trees to grow, the reason supports the assertion. By removing less desirable trees, the remaining trees can thrive better, and new growth can be encouraged.

5. **Evaluating the Options**:
- **Option 1** states that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
- **Option 2** states that both are true but the reason is not the correct explanation.
- **Option 3** states that the assertion is true but the reason is false.
- **Option 4** states that both are false.

6. **Conclusion**: Since both the assertion and reason are true, and the reason accurately explains why improvement cutting is important, the correct answer is **Option 1**.
