In terms of development, what distinguishes insects with incomplete metamorphosis?

In insects with incomplete metamorphosis, the development process involves three distinct life stages: eggs, nymphs, and adults. This developmental pattern is characterized by the absence of a pupal stage, which differentiates it from complete metamorphosis, where insects transition through larvae and pupae before reaching adulthood.

During incomplete metamorphosis, the nymph stage resembles a miniature version of the adult but lacks fully developed wings and reproductive structures. As the nymphs grow, they molt several times, gradually developing into adults. This form of development enables nymphs to adapt quickly to their environments since they can begin feeding and growing soon after hatching.

The other options are not aligned with the definition of incomplete metamorphosis. While there is an emphasis on the life stages, the critical factor here is distinguishing the specific three stages involved in this type of development, which ultimately leads to the correct identification of the transformation process.
