Question

The correct order of life stages in an insect with complete metamorphosis would be

• A. Egg $\to$ larva $\to$ adult
• B. Egg $\to$ nymph $\to$ adult
• C. Egg $\to$ nymph $\to$ larva $\to$ adult
• D. Egg $\to$ larva $\to$ pupa $\to$ adult
• E. Egg $\to$ nymph $\to$ pupa $\to$ adult

Answer 1

Answer: (D)

Egg $\to$ larva $\to$ pupa $\to$ adult

Complete metamorphosis consists of four distinct stages namely egg, larva, pupa, and adult while the incomplete/gradual/simple metamorphosis lacks pupa and has three life cycle stages: egg, nymph, and adult. Larva is a worm-like structure which eats constantly and grow rapidly into the pupa (having hard covering). The pupa is then transformed into an adult.

Therefore, the correct answer is option D.
