Hagfish and Lampreys are examples of which group?

Explanation:
Jaw structure is the key feature here. Hagfish and lampreys lack true jaws, so they belong to jawless fishes. They’re primitive vertebrates with cartilaginous skeletons rather than bone, and they don’t share the jawed, bony-skeleton features seen in other fish groups. Bony fish have jaws and a bone-based skeleton, cartilaginous fish have jaws but a cartilage skeleton, and gills are a respiratory feature, not a classification group.
