R : Leyding's cells are located between the Sertoli cells

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 but the reason is not the correct explanation of the assertion then mark (2)
C. If Assertion is true statement but Reason is false then mark (3)
D. If both Assertion and Reason are false statement then Mark (4)

Answer

### Step-by-Step Solution

1. **Understanding the Assertion**: The assertion states that Leydig's cells synthesize and secrete testicular hormones called androgens.
- Leydig's cells are also known as interstitial cells and are responsible for producing testosterone, which is a type of androgen.

2. **Understanding the Reason**: The reason states that Leydig's cells are located between Sertoli cells.
- This is incorrect. Leydig's cells are located in the interstitial space adjacent to the seminiferous tubules, not between Sertoli cells.

3. **Analyzing the Relationship**: We need to determine if the assertion and reason are true or false.
- The assertion is true because Leydig's cells do produce androgens like testosterone.
- The reason is false because Leydig's cells are not located between Sertoli cells; they are found adjacent to the seminiferous tubules.

4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false.

5. **Selecting the Correct Option**: Based on the analysis, the correct option is that the assertion is true and the reason is false.
