Assertion : Parbhani kranti is transgenic variety of Abelmoschus esculentus
Reason : Mutation breeding is useful for improving new varieties

Options

A. (a) If both assertion and reason are true and reason is the correct explanation of assertion.
B. (b) If both assertion and reason are true but reason is not the correct explanation of assertion.
C. (c) If assertion is true but reason is false.
D. (d) If both assertion and reason are false.

Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Parbhani Kranti is a transgenic variety of Abelmoschus esculentus."
- Abelmoschus esculentus is commonly known as okra or ladyfinger.
- Parbhani Kranti is indeed a variety of okra that has been developed through genetic modification.

2. **Understanding the Reason**:
- The reason states that "Mutation breeding is useful for improving new varieties."
- Mutation breeding involves inducing mutations in plants through radiation or chemicals to create new traits or characteristics. This technique is indeed used to develop improved varieties of crops.

3. **Evaluating the Truth of the Statements**:
- Both the assertion and the reason are true statements. Parbhani Kranti is a transgenic variety, and mutation breeding is a recognized method for developing new plant varieties.

4. **Assessing the Relationship Between Assertion and Reason**:
- While both statements are true, the reason does not specifically explain how Parbhani Kranti was developed. The reason is general about mutation breeding but does not link directly to the assertion about Parbhani Kranti.

5. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not explain the assertion, the correct answer is that both are true, but the reason does not support the assertion.

### Final Answer:
- Both the assertion and reason are true, but the reason does not explain the assertion.
