Which life cycle progression is described as Egg -> Larva -> Pupa -> Adult?

• A. Nematode
• B. Fish
• C. Insect
• D. Plant

Answer: (C)

Egg -> Larva -> Pupa -> Adult shows complete metamorphosis, a pattern seen in many insects. Here, the egg hatches into a larva (often worm-like and focused on feeding), the larva then enters a pupal stage (a non-feeding, transformation phase), and finally an adult emerges for reproduction and dispersal. This pupal stage is the key that distinguishes this insect lifecycle from other groups. Nematodes typically go egg–juvenile–adult without a pupal phase, fish develop from egg to juvenile to adult without a pupal form, and plants don’t undergo larva and pupa stages at all.
