Question

which term means \process of cartilage turning into bone\?
ossification
osteopathy
osteomalacia
chrondrofication

Explanation:

Ossification refers to the biological process where cartilage or other connective tissue is converted into bone. Osteopathy is a type of alternative medicine, osteomalacia is a softening of bones due to vitamin D deficiency, and "chrondrofication" is a misspelling (correct term is chondrification, which is cartilage formation, not bone conversion).

Answer:

ossification
