Solution

The correct option is B Nematode infestation
Host plant generates dsRNA that triggers protection against nematode infestation. The parasites do not survive in the transgenic host that is capable of expressing specific interfering RNA. This form of gene silencing although highly effective is a little more expensive than the creation of Bt cotton using the bacterium Bacillus thuringiensis.
