Question

Which one of the following is categorized as a parasite in true sense?

• A. The cuckoo lays its egg in crow's nest
• B. The female Anopheles bites and sucks blood from humans
• C. Human foetus developing inside the uterus draws nourishment from the mother
• D. Head louse living on the human scalp as well as laying eggs on human hair

Answer 1

The correct option is C

Human foetus developing inside the uterus draws nourishment from the mother

Head louse living on the human scalp as well as laying eggs on human hair is a parasite in true sense. Female mosquito is not considered a parasite, as it needs human blood only for reproduction. Cuckoo that lays eggs in crow's nest is a brood parasite not a parasite in true sense.
