Which one of the following is an example of carrying out biological co...
Biological control of pests/ diseases using microbes involves the use of microorganisms to control and manage pests and diseases in plants.
Bt - cotton to increase cotton yield:
Bt (Bacillus thuringiensis) is a soil bacterium that produces a protein that is toxic to many pest insects. Bt cotton is a genetically modified cotton that produces this protein, which reduces the need for chemical insecticides and increases cotton yield.
Nucleopolyhedrovirus against white rust in Brassica:
Nucleopolyhedrovirus is a virus that infects and kills certain insect pests, including the larvae of the diamondback moth, which is a major pest of Brassica crops. The use of this virus as a biological control agent can help reduce the need for chemical insecticides and improve crop yield.
Trichoderma sp. against certain plant pathogens:
Trichoderma is a genus of fungi that can be used as a biological control agent against certain plant pathogens, including Fusarium, Rhizoctonia, and Pythium species. Trichoderma sp. can colonize plant roots and produce enzymes that help control these pathogens, reducing the need for chemical fungicides and improving plant health.
All of above:
All of the above examples involve the use of microbes as a biological control agent to manage pests and diseases in plants. These methods are environmentally friendly and sustainable and can help reduce the use of chemical pesticides and fungicides, which can have negative impacts on human health and the environment.

1.BT cotton is genetically modified plant in which bascillus thruingiensis toxin genes are introduced into plants. such plants are resistant to attack by insect pest so, result in increased yield.
2.nucleopolyhedrovirus are biological control agents these are used for narrow spectrum insecticidal applications these are used in resistance to white rust causing fungi in brassica.
3.Trichoderma species are free living fungi that are very common in the root ecosystem they are effective biocontrol agents of several plant pathogens.
4.ladybird beetle is used in wheat plant to control Aphids not in mustard...
so,now u can see option A,B C are correct..
I am not very sure abt option 4 ..
