The correct option is C Bacillus thuringiensis
Bt cotton/ brinjal
Bt cotton/ Bt brinjal is a genetically modified plant. Bt in Bt cotton stands for the bacterium, Bacillus thuringiensis. The bacterium has the cry gene which encodes insecticidal crystal proteins. Hence, this gene is isolated and introduced into certain crops which frequently get attacked by the target insects. The genetically modified crop becomes resistant to the target insect and is prefixed with ‘Bt’.
Final answer
Bacillus thuringiensis
