Egg parasitoid?

Correct option is A

An egg parasitoid is an organism that lays its eggs in or on the eggs of another insect, leading to the parasitism of the host insect's eggs. Trichogramma is a genus of tiny wasps that are widely used as biological control agents in agriculture. They are known as egg parasitoids because their larvae develop inside the eggs of various insect pests, preventing the hatching of the pest larvae.
