Ovipositor longer than body can be found in

Answer: Option C

Ovipositors longer than the body can be found in Ichneumonidae.
Ovipositors longer and more slender than stingers of aculeate wasps. Ichneumonid females have an unmodified ovipositor which they use to lay eggs inside or on their host.
Ichneumonids generally inject venom along with the egg, but only larger species with relatively short ovipositors use the ovipositor in defense. Ovipositors modified for prey capture and defense, and do not pass their eggs along the stinger.
