A pupal stage indicates a complete life cycle.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Understanding metamorphosis styles helps here. In complete metamorphosis, development follows egg → larva → pupa → adult, with major transformation during the pupal stage. Seeing a pupal stage means the organism is undergoing this kind of life cycle, with four distinct life stages, including the pupal phase that leads to the adult. In contrast, incomplete metamorphosis has no pupal stage—the young (nymphs) resemble small adults and gradually molt to full size. So a pupal stage is a hallmark of a complete life cycle, making the statement true.
