Which of the following is a genetically modified crop listed among examples?

• A. Non-GMO corn
• B. Banana
• C. Bt cotton
• D. Rice

Answer: (C)

Genetically modified crops are plants engineered to carry new traits by adding or altering genes. Bt cotton is a classic example because it contains a gene from Bacillus thuringiensis that makes the plant produce Bt toxin. This toxin targets specific pest insects, giving the crop built-in pest protection and often reducing the need for chemical pesticides. That trait—pest resistance introduced through genetic modification—is what makes Bt cotton the correct example.

Non-GMO corn is labeled as not genetically modified, so it isn’t a GM crop. Banana and rice can be grown in conventional ways or modified in some contexts, but among the options given, Bt cotton is the well-known, widely recognized genetically modified crop.
