Assertion : In head inflorescence , florets are arranged centrifugally .
Reason : There are always two types of florets in head.

Options

A. If both Assertion and Reason are true and the Rea-son is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Rea-son is not the correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If Assertion is wrong and Reason is right

Answer

To analyze the given question, we will break it down into two parts: the Assertion and the Reason.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that in head inflorescence, florets are arranged centrifugally.
- In botanical terms, "centrifugally" means that the florets are arranged outward from the center.

2. **Evaluating the Assertion**:
- In head inflorescence (also known as capitulum), the florets are actually arranged centripetally, meaning they are arranged inward towards the center.
- Therefore, the assertion is **incorrect**.

3. **Understanding the Reason**:
- The reason states that there are always two types of florets in head inflorescence.
- In head inflorescence, typically, there are two types of florets: ray florets (which are usually found on the outer edge) and disk florets (which are found in the center).

4. **Evaluating the Reason**:
- This statement is **correct** as it accurately describes the presence of two types of florets in head inflorescence.

5. **Conclusion**:
- Since the assertion is incorrect and the reason is correct, we can conclude that the relationship between the two statements does not hold.
- Therefore, the correct answer is that the assertion is false, but the reason is true.

### Final Answer:
The assertion is incorrect, and the reason is correct.
