B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False .
D. If both Assertion & Reason are False.

Answer

To solve the question, we need to analyze the assertion and the reason provided:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Formation of sperm takes place in seminiferous tubules of testes."
- This statement is true because sperm production (spermatogenesis) occurs in the seminiferous tubules located within the testes.

2. **Understanding the Reason**:
- The reason states that "Seminiferous tubules are lined with male germ cells and Sertoli cells."
- This statement is also true. The seminiferous tubules contain male germ cells (spermatogonia, spermatocytes, etc.) and Sertoli cells, which support and nourish the developing sperm cells.

3. **Evaluating the Relationship**:
- While both the assertion and reason are true, we need to determine if the reason correctly explains why the assertion is true.
- The reason describes the composition of the seminiferous tubules but does not directly explain the process of sperm formation. It does not clarify how the presence of these cells leads to sperm production.

4. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not provide a correct explanation for the assertion, the correct answer is:
- **(b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.**
