Insects that undergo complete metamorphosis pass through which sequence?

Insects that undergo complete metamorphosis pass through which sequence?

• A. Parthenogenesis
• B. Nymph, Egg, Adult
• C. Egg, Larva, Pupa, Adult
• D. Gradual Metamorphosis

Answer: (C)

Insects that undergo complete metamorphosis experience four distinct life stages in a set sequence: egg, larva, pupa, and adult. The larva typically looks very different from the adult and usually has a different lifestyle, while the pupa is a nonfeeding stage where tissues are reorganized to become the adult form. This dramatic transformation reduces competition for resources between young and mature insects and explains why the correct sequence is egg → larva → pupa → adult. The other options don’t fit because parthenogenesis refers to asexual reproduction, and incomplete metamorphosis follows a egg → nymph → adult path (with nymphs resembling small adults); gradual metamorphosis is another term for that incomplete type.
