Solution

The correct option is A Nucleopolyhedrovirus
Trichoderma are fungi and present in the soil as avirulent symbionts.
Agrobacterium has a unique ability to transfer its DNA to the plants and hence it is manipulated by genetic engineering to make the crop pathogen resistance.
But the biocontrol agent for several plant pathogens is Nucleopolyhedrovirus. It is a virus that infects the pests like butterfly, moth, etc.
So the correct answer is ' Nucleopolyhedrovirus'.
