  • Correct answer
    D
    (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Solution

Bacillus thuringiensis is a bacterium used as a biocontrol agent against lepidopteran insects, such as the cabbage worm.

Beauveria bassiana is a fungus that acts as a parasite on various arthropod species, causing white muscardine disease, and is used to control pests like mealy bugs.

Nosema locustae is a microsporidian parasite specifically used as a biological control agent against grasshoppers and locusts.

Nucleopolyhedrovirus (NPV) is a type of baculovirus that is highly species-specific and is widely used for the control of the gypsy moth.

Therefore, the correct matching is (A) - (III), (B) - (IV), (C) - (I), (D) - (II).

Answer: (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hence, the correct answer is option: 'D'.
