6. The process of bone formation and breakdown is called:

• A. Ossification
• B. Resorption
• C. Remodeling
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Remodeling.' Bone remodeling is the continuous process of bone formation (ossification) and breakdown (resorption). Ossification refers to the formation of bone tissue, while resorption is the breakdown and removal of old bone tissue. The term 'remodeling' encompasses both of these processes, making it the most appropriate choice. While ossification and resorption are part of bone remodeling, they do not cover the entire process on their own, hence 'All of the above' is incorrect.
