Why is cartilage important? a. it contains a fluid that enables the surfaces of bones to slide over each other smoothly at the joints. b. it acts as a cushion between bones and protects them as they move against each other. c. it holds bones together at the joints. d. it causes bones to fuse together as they grow.

The correct answer is option B.

Explanation:

Cartilage refers to a flexible and robust kind of connective tissue, which is found inside a body. Connective tissues play important roles in the body. The prime structural constituents of the bodies are muscle, bone, and cartilage. Bones are tough and rigid, while the muscles stretch, bend, and are flexible in nature.  

The cartilage connective tissue acts as a cushion between the bones and the muscles. It is not as tough or as firm as bones and is also less elastic in comparison to muscles. Thus, cartilage is found in the locations where one requires some composition and support, however, some sort of flexibility as well. This comprises the places like the ears, the joints, nose, and in between the vertebrae in the spinal column.
