The difference between gradual metamorphosis and complete metamorphosis is described as:

• A. Pupae look like larvae
• B. Adults never molt
• C. Nymphs resemble adults but lack wings
• D. Eggs are laid in water only

Answer: (C)

Gradual metamorphosis involves immature stages called nymphs that resemble the adults and grow through molts, with wings developing as wing pads and appearing only in the final molt. Saying that nymphs resemble adults but lack wings describes this pattern precisely: the young look like smaller versions of the adults and there is no separate pupal stage.

In contrast, complete metamorphosis includes a larval stage that looks very different from the adult and a pupal stage where major transformation takes place; wings typically form during or after the pupal stage. The other statements don’t capture this fundamental difference—the presence or absence of a pupal stage and the distinct larval form.
