• B. (i) and (iii)
• C. (ii) and (iii)
• D. (i), (ii) and (iii)

Answer 1

The correct option is C (ii) and (iii)

Trichoderma are free-living fungi that live on root surfaces. They are useful as biocontrol agents and are not harmful to plants. Infact, most trichoderma can be characterized as useful plant symbionts. Baculoviruses are viruses that are obligate parasites of insects and other arthropods. These can be used as specific biocontrol agents as they do not harm any non-target insects or plants or animals.
