Cry genes are divided into three categories. These genes are in charge of producing crystalline proteins, which aid in the eradication of pests. Cry IAC, Cry IAB, and Cry IIAB are the cry genes. The corn borer pest is controlled by the gene cry IAB. The genes cry IAC and cry IIAB are in charge of controlling bollworms that attack cotton plants.
Therefore, C is the correct option.
