Which of the following is an example of a cartilaginous fish?

Explanation:
Cartilaginous fish have skeletons made mostly of cartilage rather than bone, which makes them lighter and more flexible. Sharks fit this group, so they’re an example of a cartilaginous fish. The other options—Salmon, Tuna, and Clownfish—are bony fish, meaning their skeletons are primarily bone and they typically have a swim bladder to help with buoyancy. This difference between cartilage and bone in the skeleton is what sets cartilaginous fish like sharks apart from the others.
