Assertion : In the human the temperature of scrotum is `2-2.5^(@)C` lesser then normal body temperature .
Reason : Formation of sperm does not occur at normal core body temperature .
(a) If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion .
(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.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion .
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 evaluate the assertion and reason provided:

**Assertion**: In humans, the temperature of the scrotum is 2-2.5°C lower than normal body temperature.
**Reason**: Formation of sperm does not occur at normal core body temperature.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the temperature of the scrotum is lower than the normal body temperature.
- Normal human body temperature is approximately 37°C, so the scrotum's temperature being 2-2.5°C lower means it is around 34.5-35°C.

2. **Understanding the Reason**:
- The reason given is that sperm formation (spermatogenesis) does not occur at normal core body temperature.
- This is true because sperm production requires a cooler environment than the core body temperature to be efficient.

3. **Evaluating the Truth of Both Statements**:
- Both the assertion and the reason are true. The scrotum's lower temperature is essential for the proper formation of sperm.

4. **Determining the Relationship**:
- The reason explains why the assertion is true. The cooler temperature in the scrotum is necessary for sperm formation, which cannot happen effectively at the higher core body temperature.

5. **Conclusion**:
- Since both the assertion and reason are true, and the reason correctly explains the assertion, the correct answer is (a): If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.

### Final Answer:
(a) If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
