Which statement describes a life cycle with incomplete metamorphosis?

The life cycle with incomplete metamorphosis is characterized by three main stages: egg, nymph, and adult. In this process, the organism hatches from an egg into a nymph, which resembles a smaller version of the adult but lacks fully developed wings and reproductive structures. As the nymph matures, it undergoes a series of molts, gradually developing into the adult form.

This contrasts with complete metamorphosis, which involves a larval stage and the formation of a pupa. The options that include larva and pupa, like the one featuring egg, larva, pupa, and adult, describe complete metamorphosis. The presence of specific stages like caterpillar or pupa in the other choices further indicates complete metamorphosis scenarios. Thus, the description of egg, nymph, adult correctly outlines the stages of insects that undergo incomplete metamorphosis, such as grasshoppers and true bugs.
