Question:
Assertion (A): The activated osteoblasts start deposition of mineral material to join fractured bone.
Reason (R): The major part of inorganic matter of bone is collagen.
Assertion (A): The activated osteoblasts start deposition of mineral material to join fractured bone.
Reason (R): The major part of inorganic matter of bone is collagen.
Reason (R): The major part of inorganic matter of bone is collagen.
Show Hint
Calcium salts = inorganic; collagen = organic protein matrix in bones.

- Both A and R are correct and R is the correct explanation of A.
- Both A and R are correct but R is not the correct explanation of A.
- A is correct but R is incorrect.
- A is incorrect but R is correct.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Osteoblasts are responsible for the deposition of calcium phosphate to repair and join fractured bone, which makes assertion true. However, collagen is an organic component, not an inorganic part of bone; hence the reason is incorrect.
