Assertion (A): In human male, testes are extra abdominal organs which are present inside scrotum.
Reason ( R): Scrotum has a relatively lower temperature needed for the production and storage of sperms.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A.
C. A is true but R is false.
D. A is false and R is true.

Explanation

To analyze the given assertion and reason, we can break it down into steps:

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that in human males, the testes are extra-abdominal organs located inside the scrotum.
- This is true because the testes develop in the abdominal cavity during fetal development and later descend into the scrotum before birth.

2. **Understanding the Reason (R)**:
- The reason provided states that the scrotum has a relatively lower temperature necessary for the production and storage of sperm.
- This is also true. The optimal temperature for sperm production is indeed lower than the normal body temperature, which is why the testes are located outside the body in the scrotum.

3. **Evaluating the Relationship**:
- Both the assertion and the reason are correct statements.
- The reason explains why the assertion is true; the lower temperature in the scrotum is essential for the proper functioning of the testes.

4. **Conclusion**:
- Since both the assertion and reason are correct and the reason supports the assertion, the correct answer is that both the assertion and reason are true.

### Final Answer:
Both Assertion (A) and Reason (R) are correct, and the reason supports the assertion.
