Which option is an example of a biological control of pests?

• A. Integrated pest management
• B. Species specific pesticides
• C. Chemical pesticides
• D. Biological control of pests

Answer: (D)

Biological control of pests uses living organisms to reduce pest populations. It relies on natural enemies—predators, parasites, or pathogens—to keep pests in check without using chemicals. The option that explicitly states biological control of pests matches this idea and serves as a direct example of using living organisms to manage pests. Integrated pest management is a broader approach that may combine biological control with other methods, so it’s not a single biological method by itself. Chemical and species-specific pesticides are chemical approaches, not biological ones.
