Assertion : GM salmon was the first transgenic animal for performing vaccine safety tests
Reason : For the production of GM salmon, genetically modified ova were fused with normal sperms of the same species.

Options

A. If both assertion and reason are true and 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-reason question regarding GM salmon, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that GM salmon was the first transgenic animal for performing vaccine safety tests. We need to evaluate whether this statement is true or false.

2. **Evaluating the Assertion**: GM salmon, specifically the AquAdvantage salmon, was primarily developed for food production purposes, particularly to grow faster than non-transgenic salmon. There is no substantial evidence that it was the first transgenic animal used for vaccine safety tests. Therefore, the assertion is **false**.

3. **Understanding the Reason**: The reason provided states that GM salmon was produced by fusing genetically modified ova with normal sperm of the same species.

4. **Evaluating the Reason**: In reality, GM salmon was created by using normal ova (eggs) and genetically modified sperm. The genetic modification involved adding a gene that promotes growth. Thus, the reason is also **false**.

5. **Conclusion**: Since both the assertion and the reason are false, we can conclude that the correct answer is that both the assertion and reason are false.

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