Assertion : The acrocentric chromosome has centromere at the terminal position.
Reason : The metacentric chromosome has centromere slightly away from the middle of the chromosome.

Options

A. If both assertion and reason are true amnd reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the assertion and reason question, we need to analyze both statements carefully.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states: "The acrocentric chromosome has the centromere at the terminal position."
- **Analysis**: In acrocentric chromosomes, the centromere is located closer to one end, but it is not at the terminal position. Instead, it creates a long arm (Q-arm) and a very short arm (P-arm). Thus, this statement is **false**.

2. **Understanding the Reason**:
- The reason states: "The metacentric chromosome has the centromere slightly away from the middle of the chromosome."
- **Analysis**: In metacentric chromosomes, the centromere is located approximately in the middle of the chromosome, dividing it into two arms of roughly equal length. Therefore, this statement is also **false**.

3. **Conclusion**:
- Since both the assertion and the reason are false, the correct answer is that both the assertion and reason are false.

### Final Answer:
Both assertion and reason are false.
