Some of the characteristics of Bt cotton are:

1. long fibre and resistance to aphids
2. medium yield, long fibre and resistance to beetle pests
3. high yield and production of toxic protein crystals which kill dipteran pests
4. long fibre and resistance to bollworms

Correct answer: long fibre and resistance to bollworms

Solution

Bt cotton contains a gene from Bacillus thuringiensis that produces a toxin lethal to bollworms, which are major cotton pests. Its key characteristic is resistance to bollworms; long fibre is a desirable cotton trait but not the defining Bt feature.
