Assertion: Middle piece of the sperm is called its powerhouse'.
Reason: Sperms are motile bodies

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the middle piece of the sperm is referred to as its "powerhouse." This is based on the fact that the middle piece contains mitochondria, which are responsible for energy production.

2. **Understanding the Reason**: The reason provided states that sperms are motile bodies. This means that sperm cells are capable of movement, which is essential for their function in reproduction.

3. **Analyzing the Relationship**: While both the assertion and reason are true, we need to determine if the reason correctly explains the assertion. The assertion is about the middle piece being the powerhouse due to the presence of mitochondria, while the reason focuses on the motility of sperm.

4. **Conclusion**: The reason does not directly explain why the middle piece is called the powerhouse. The correct explanation would relate to the energy provided by mitochondria for movement, not just the fact that sperm are motile. Therefore, while both statements are true, the reason is not the correct explanation for the assertion.

5. **Final Answer**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
