Rickets is a condition believed to result from a deficiency of which vitamin?

1. Vitamin B12

2. Vitamin D

3. Vitamin K

4. Vitamin A

The correct answer is: Vitamin D

Rickets is a disorder that primarily affects bone development in children and is characterized by soft and weakened bones. This condition is most commonly associated with a deficiency of Vitamin D. Vitamin D plays a crucial role in calcium and phosphorus absorption in the body, which are essential nutrients for bone health. When there is insufficient Vitamin D, the body struggles to absorb calcium effectively, leading to the softening of bones as seen in rickets. While Vitamin A, B12, and K have important roles in the body—including immune function, red blood cell formation, and blood clotting, respectively—they are not directly implicated in the development of rickets. Vitamin D's primary importance in this context relates to its function in maintaining proper levels of calcium and phosphorus, making it central to preventing rickets.
