Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Hyaline cartilage and fibrocartilage are similar in that they are mostly made of collagen proteins. The difference is in the way they are arranged. Hyaline cartilage consists of rounded collagen which makes it hard and like marble. It is usually found in movable joints. Fibrocartilage contains both types I and type II fibres arranged in bundles. This makes it strong and slightly flexible and commonly found as intervertebral discs in the spine.
