Assertion : Axillary buds, in actively growing herbaceous plants, generally remain dormant
Reason :This is due to apical dominance which is under the influence of auxins

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

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 axillary buds in actively growing herbaceous plants generally remain dormant.
- Axillary buds are located in the axil of leaves and are responsible for lateral growth.

2. **Understanding the Reason**:
- The reason provided is that this dormancy is due to apical dominance, which is influenced by auxins.
- Apical dominance is a phenomenon where the main central stem of the plant grows more strongly than the side stems. This is primarily due to the production of auxins by the apical bud.

3. **Linking Assertion and Reason**:
- The assertion is correct because axillary buds do remain dormant in actively growing herbaceous plants.
- The reason is also correct as apical dominance, facilitated by auxins produced by the terminal bud, inhibits the growth of axillary buds.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true and the reason is the correct explanation for the assertion.

### Final Answer:
Both the assertion and the reason are correct, and the reason is the correct explanation of the assertion.
