Which vitamin deficiency leads to the bone-softening disease known as rickets in children and osteomalacia in adults?

💡 Solution & Explanation

Vitamin D deficiency impairs the proper metabolism of calcium and phosphorus, leading to defective bone mineralization that manifests as rickets in growing children and osteomalacia in adults. In contrast, shortages of Vitamin C cause scurvy, while Vitamin A deficiency results in night blindness.
