Correct Answer: Shark and Ray

Solution : The correct option is Shark and Ray

Cartilaginous Fish (Chondrichthyes) have skeletons made of cartilage, which is a tough, flexible tissue (similar to the material in your nose and ears) rather than true bone. This group includes sharks, rays, and skates. Sharks have sharp, replaceable teeth and are known for their cartilaginous skeletons. Rays have flattened bodies and often have a disc-like shape, while skates are similar but smaller and more kite-shaped. Other fishes like eel, hilsa, tune are Bony Fish (Osteichthyes).
