Assertion: Few of repetitive sequence are called jumping genes.
Reason: They jump at place of location and do not change their position.

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 Reasom are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "few of the repetitive sequences are called jumping genes."
- Jumping genes, also known as transposons, are indeed a type of repetitive DNA sequence that can move within the genome.

2. **Understanding the Reason**:
- The reason provided is "They jump at place of location and do not change their position."
- This statement is misleading because jumping genes (transposons) actually do change their position within the genome. They can move from one location to another.

3. **Evaluating the Assertion**:
- Since jumping genes are classified as repetitive sequences that can move, the assertion is **true**.

4. **Evaluating the Reason**:
- The reason incorrectly describes the behavior of jumping genes. They do not remain in one place; instead, they can relocate within the genome. Therefore, the reason is **false**.

5. **Conclusion**:
- The assertion is true, but the reason is false. Thus, the correct relationship is that the assertion is correct, but the reason does not correctly explain the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: False
- **Explanation**: The assertion is correct because jumping genes are indeed repetitive sequences that can move. However, the reason is incorrect because jumping genes do change their position within the genome.
