Which option correctly describes a key characteristic of the beetle order Coleoptera?

Beetles are defined by forewings that have hardened into protective elytra, which cover the hind wings when the insect is not flying. They also have chewing mandibles and undergo complete metamorphosis, meaning their life cycle includes egg, larva, pupa, and adult. The description that includes forewings hardened into elytra covering the hind wings, chewing mouthparts, and complete metamorphosis best fits this order. Other descriptions mix traits from different insect groups—such as membranous forewings, siphoning mouthparts, or incomplete metamorphosis—which do not characterize beetles.
