In each of the following questions, a statement of Assertion is given followed by corresponding statement of Reason of the statement, mark the correct alternative as directed below.
Assertion : Meiotic division occurs in reproductive cells.
Reason: Synapsis occurs during zygotene of meiosis.

Options

A. If both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason 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.

Answer

To analyze the given question, we need to evaluate the Assertion and the Reason provided:

**Assertion:** Meiotic division occurs in reproductive cells.
**Reason:** Synapsis occurs during zygotene of meiosis.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- Meiotic division, also known as meiosis, is a specialized type of cell division that occurs in reproductive cells (gametes). This process is crucial for sexual reproduction as it reduces the chromosome number by half, resulting in haploid cells.

2. **Understanding the Reason:**
- The reason states that synapsis occurs during zygotene of meiosis. Synapsis is the pairing of homologous chromosomes during prophase I of meiosis, specifically in the zygotene stage. This is an important event that allows for crossing over, which contributes to genetic variation.

3. **Evaluating the Truth of Each Statement:**
- Both the assertion and the reason are true statements:
- **Assertion:** True, as meiosis occurs in reproductive cells.
- **Reason:** True, as synapsis indeed occurs during the zygotene stage of meiosis.

4. **Determining the Relationship Between Assertion and Reason:**
- While both statements are true, the reason provided does not directly explain why meiotic division occurs in reproductive cells. The assertion speaks to the occurrence of meiosis in reproductive cells, while the reason describes a specific event (synapsis) during one phase of meiosis.

5. **Conclusion:**
- The correct alternative to mark would be that both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
