Assertion (A): The leydig cells of testis are present outside the seminiferous tubules.
Reason (R): Testis helps to synthesise and secrete hormones called androgens.

Options

A. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion(A).
B. Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
C. Assertion (A) is true but reason (R) is false.
D. Assertion (A) is false but reason (R) is true.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion (A):**
- The assertion states that Leydig cells are located outside the seminiferous tubules of the testes.
- Leydig cells are indeed found in the interstitial space between the seminiferous tubules.

2. **Understanding the Reason (R):**
- The reason provided states that the testes synthesize and secrete hormones known as androgens.
- Leydig cells are responsible for the production of androgens, such as testosterone, which are crucial for male reproductive functions.

3. **Analyzing the Relationship Between Assertion and Reason:**
- Since Leydig cells are located outside the seminiferous tubules and are responsible for producing androgens, the reason supports the assertion.
- Both statements are true, and the reason correctly explains why the assertion is true.

4. **Conclusion:**
- Therefore, both the assertion and the reason are correct, and the reason is the correct explanation for the assertion.

**Final Answer:**
Both assertion (A) and reason (R) are true, and the reason is the correct explanation of the assertion.
