Verified by Experts

The correct Answer is:
C
Out of the given statement 'c' is correct example because Bt cotton is Genetically Modified (GM) cotton which has an incorporated gene extracted from the bacterium Bacillus thuringiensis . This gene codes for Bt toxin in plant tissues which is harmful only to a small fraction of insects , most notably the larvae of lepidopterans, moths , butterflies , beetles, flies, etc, and harmless to other forms of life. So, it is used as biological control of pests/diseases.
