Options

A. if both are true with reason being correct explanation
B. both true but reason is not correct explanation
C. assertion true but reason is wrong
D. both are wrong

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Flavr-Savr tomato was the first transgenic commercial crop that entered the market."
- **Verification**: The Flavr-Savr tomato was indeed the first genetically modified organism (GMO) approved for human consumption. It was developed to have a longer shelf life and more flavor compared to conventional tomatoes. This assertion is **true**.

2. **Understanding the Reason**: The reason provided is "Roundup variety of Soybean was prepared through breeding."
- **Verification**: The Roundup Ready soybean is a genetically modified variety that has been engineered to be resistant to glyphosate, a herbicide. This modification was achieved through genetic engineering, not traditional breeding methods. Therefore, this statement is **false**.

3. **Conclusion**: Since the assertion is true and the reason is false, we conclude that the correct relationship is that the assertion is true, but the reason does not correctly explain the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: False
- The correct option is that the assertion is true and the reason is false.
