Which of the following statements is true?
a. endochondral ossification leads to the formation of the clavicles and cranial bones.
b. endochondral ossification occurs within fibrous connective tissue membranes.
c. during endochondral ossification, hyaline cartilage is broken down and replaced with bone.
d. most bones in the body are formed by intramembranous ossification.

The correct answer is statement c.

Explanation:

The procedure of the development of bones from hyaline cartilage is known as endochondral ossification. Endochondral ossification transforms hyaline cartilage into true bones, that is, hyaline cartilage functions as a template for the formation of bones. All the bones of the body, except for the mandible, flat bones of the skull, and clavicles are produced via endochondral ossification.
