✓ Correct answer: D. Vitamin DVitamin D deficiency is most commonly associated with rickets, which is characterized by the softening and weakening of bones in children. This condition leads to skeletal deformities such as bowed legs. Vitamin D is essential for calcium absorption, and without sufficient Vitamin D, bones cannot properly mineralize, leading to rickets. Iron is crucial for preventing anemia, while calcium also plays a critical role in bone health but requires Vitamin D for proper absorption. Vitamin C is important for immune function and collagen synthesis but is not directly related to preventing rickets.
