Which nutrient is essential for strong bones?

Explanation:
Calcium provides the mineral strength of bones by forming hydroxyapatite crystals in the bone matrix, making bones hard and resistant to fractures. Adequate calcium intake supports peak bone mass in youth and helps maintain bone density later in life. Vitamin D matters too because it helps the body absorb calcium, but the nutrient that directly contributes to bone strength is calcium. The other options have different roles: vitamin C supports collagen in the bone matrix but doesn’t supply the mineral strength; iron and vitamin B12 are important for blood and energy, not bone mineralization.
