The Correct Option is B

Solution and Explanation

Bt cotton has a gene from Bacillus thuringiensis bacterium inserted, making the plant produce a pest-killing protein. This is an extra gene borrowed from nature, not fully lab-designed DNA, and resistance is specific to pests (bollworm), not diseases in general or growth speed.

Final Answer: Option (2).
