Question

which of the following is true about bones? blood vessels have zero involvement with bones. all bones are mostly cartilage. ossification is the process of bone development.

Explanation:

• Analyze the first option: Bones have blood vessels (e.g., for nutrient supply), so "Blood vessels have zero involvement with bones" is false.
• Analyze the second option: Most bones are not mostly cartilage (cartilage is present in developing bones but replaced in mature bones), so "All bones are mostly cartilage" is false.
• Analyze the third option: Ossification is indeed the process of bone development (formation of bone tissue from cartilage or other connective tissue), so this statement is true.

Answer:

Ossification is the process of bone development.
