Incomplete metamorphosis life stages include which of the following?

Incomplete metamorphosis life stages include which of the following?

• A. Egg, nymph, and adult
• B. Egg, larva, and adult
• C. Egg, pupa, and adult
• D. Nymph and adult

Answer: (A)

The question tests the pattern of life stages in incomplete metamorphosis, where the young are nymphs that resemble adults and there is no pupal stage. In incomplete metamorphosis, the life cycle goes from egg to nymph to adult, with nymphs gradually developing into adults through molts and never forming a pupal stage. The best choice lists egg, nymph, and adult, which directly matches this three-stage pattern. The other options introduce a larval or pupal stage (which belong to complete metamorphosis) or omit the egg stage entirely, so they don’t fit incomplete metamorphosis.
