Detailed explanation-2: -Endochondral ossification is the mechanism responsible for the formation of all long bones of the axial skeleton (vertebrae and ribs) and the appendicular skeleton (limbs).

Detailed explanation-3: -Answer and Explanation: The correct answer is option (b) cartilage is replaced by bone.
