Which description correctly defines holometabolous metamorphosis?

Complete metamorphosis is defined by four distinct life stages: egg, larva, pupa, and adult. The larval stage is usually very different in form and ecology from the adult, focusing on feeding and growth, while the pupal stage is a transformation phase where the body is reorganized to become the adult. The final adult is typically morphologically distinct and often specialized for reproduction and dispersal. This four-stage sequence—egg, larva, pupa, adult—best captures holometabolous metamorphosis. Other sequences either replace the larval stage with a nymph, which indicates incomplete metamorphosis, or mix stages in a way that doesn’t reflect the complete reorganization that occurs during the pupal stage.
