Solution

The correct option is B Death of the worm
Worms feed on cotton plants and kill them. The Bt Cotton contains the bacterial cry genes, which gets activated when the worms feed on it. The alkaline pH of the worms activates the cry genes and kills the worms, thereby protecting crops from worm infestation.
