• A. Bollgard
• B. Flavr savr
• C. Liberty link
• D. Bt brinjal

Hint:

Flavr Savr tomato:
- First commercialized GM crop (1994).
- Delayed ripening due to antisense PG gene.
- Bollgard cotton was commercialized later (1996).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of the history of transgenic crops.

Step 2: Detailed Explanation:
Flavr Savr tomato was the first commercialized transgenic crop.
It was developed by Calgene in 1994.
It had delayed ripening due to antisense polygalacturonase gene.
Bollgard (A): Bt cotton (commercialized later in 1996).
Liberty link (C): Herbicide-resistant crops.
Bt brinjal (D): Not the first (developed later).
Thus, Flavr Savr was the first commercialized transgenic crop.

Step 3: Final Answer:
Thus, Flavr Savr was the first commercialized transgenic crop, which corresponds to option (B).
