Solution

The correct option is C Midgut epithelial cells
The insecticidal protein in Bt cotton, which is cry protein, binds to the midgut epithelial cells of insects. The activated toxin binds to the midgut of epithelial cells and creates pores, thereby causing swelling and lysis of the epithelial tissues. This results in the death of the insect.
