Beriberi is a disease caused by a deficiency of Vitamin B1 (Thiamine). Scurvy is caused by a deficiency of Vitamin C (Ascorbic Acid). Rickets is a condition in children caused by a deficiency of Vitamin D, calcium, or phosphate, leading to soft and weak bones. Osteomalacia is the equivalent condition in adults, primarily caused by Vitamin D deficiency. Pneumonia is an infection of the lungs, usually caused by bacteria or viruses, not a vitamin deficiency. Therefore, Rickets is caused by Vitamin D deficiency.

Vitamin D is essential for calcium and phosphate absorption and bone health. Deficiency can lead to impaired bone mineralization, resulting in Rickets in children and Osteomalacia in adults.

Vitamin D can be obtained from certain foods (fatty fish, fortified foods) and is synthesized in the skin upon exposure to sunlight. Sunlight exposure is a significant source of Vitamin D for many people.
