Which statement best describes complete metamorphosis (holometabolism) in insects?

Explanation:
In complete metamorphosis, the insect goes through four life stages: egg, larva, pupa, and adult. The larva and adult look very different and usually have different lifestyles, and a pupal stage is when the body is reorganized into the adult form. This four-stage pattern with a distinct larval form and a pupal stage is what defines holometabolism. Examples include butterflies, beetles, bees, and flies. The other patterns skip a pupal stage or have nymphs that resemble adults, which aligns with incomplete metamorphosis or direct development rather than holometabolism.
