Correct Answer: Option (B) — Only three

Concept & Option Breakdown

Standard Reference Verified

A parasitoid is an organism whose larvae live as parasites that eventually kill their host.

  • Wasps (e.g., ichneumonid and braconid wasps), Flies (e.g., tachinid flies), and certain species of Beetles (including some carabid/ground beetles) have evolved parasitoid life strategies.
  • Centipedes are predators (not parasitoids).
  • Termites are detritivores/social insects that feed on cellulose/dead wood (not parasitoids).

Hence, parasitoid species are found among three of the listed groups: Carabid beetles, Flies, and Wasps.
