A : At the end of juvenility, the organism develops the capacity to reproduce.
R: It represents the time period between the first and next flowering in plants.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true and the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statements but Reason is false then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "At the end of juvenility, the organism develops the capacity to reproduce."
- This is true because the juvenile phase is the stage before an organism reaches maturity. After this phase, the organism enters the reproductive phase where it can reproduce.

2. **Understanding the Reason**:
- The reason given is "It represents the time period between the first and next flowering in plants."
- This statement is not universally true. While it may apply to monocarpic plants (which flower only once), it does not apply to polycarpic plants (which can flower multiple times). Therefore, this reason is incorrect as it does not apply to all plants.

3. **Evaluating the Relationship**:
- Since the assertion is true and the reason is false, we conclude that the reason does not correctly explain the assertion.

4. **Selecting the Correct Option**:
- Based on the evaluation, the correct answer is that the assertion is true, but the reason is false.

### Final Answer:
- **Assertion (A)**: True
- **Reason (R)**: False
- **Correct Option**: Assertion true, reason false.
