Explanation:

Bones are composed of a matrix of collagen fibers and a mineral component. The primary mineral in bone is calcium. Calcium is an essential mineral for bone health as it provides strength and rigidity to the bone structure. Oxygen is a gas and not a mineral. Sodium, potassium, and iron are minerals but are not the primary mineral in bone. Sodium is involved in fluid balance, potassium in nerve and muscle function, and iron in oxygen transport in the blood.
