Assertion: A gene bank should not be regarded as a plant museum.
Reason: The germplasms stored in the gene bank are actively utilised by breeders to develop novel varieties.

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

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that a gene bank should not be regarded as a plant museum. This implies that the purpose and function of a gene bank are different from that of a museum.

2. **Defining a Gene Bank**: A gene bank is a facility that stores genetic material, such as seeds, pollen, and other reproductive cells. This genetic material is preserved for future use, particularly in breeding programs.

3. **Defining a Plant Museum**: A plant museum, on the other hand, typically houses dried specimens or preserved plants for educational and display purposes. It does not serve an active role in breeding or genetic research.

4. **Analyzing the Reason**: The reason provided states that the germplasm stored in the gene bank is actively utilized by breeders to develop novel varieties. Germplasm refers to the genetic material that can be used for breeding new plant varieties.

5. **Connecting Assertion and Reason**: The assertion is correct because a gene bank is not just a storage facility like a museum; it plays an active role in plant breeding. The reason supports the assertion by explaining how the stored germplasm is used in breeding programs.

6. **Conclusion**: Both the assertion and reason are true, and the reason provides a correct explanation for the assertion. Therefore, the answer is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer:
Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
