Answer: Option C

Solution

Answer: Option C
Solution:
Cotton variety Abhadita is resistant to Bollworms.
Bt cotton is a genetically modified pest resistant plant cotton variety, which produces an insecticide to combat bollworms. Bt toxins are insecticidal to the larvae of moths and butterflies, beetles, cotton bollworms and flies but are harmless to other forms of life.
China first planted Bt cotton in 1997 specifically in response to an outbreak of cotton bollworm, Helicoverpa armigera, that farmers were struggling to control with conventional pesticides.
