D Correct answer
Explanation

Sharks have skeletons made entirely of cartilage, a flexible connective tissue, rather than bone. This makes them lighter and more agile swimmers. Cartilaginous fish also include rays and skates. Option D is correct. Bones (A) are found in bony fish, while muscles (B) and tendons (C) are soft tissues, not skeletal structures.
