Vitamins and deficiency diseases MCQ - Practice Questions with Answers

Beriberi is caused by a deficiency of thiamine, which belongs to the Vitamin B group and is commonly called Vitamin B1. Severe weakness, nerve problems and cardiac symptoms can appear when thiamine is deficient, so supplementation through diet and medicine targets Vitamin B. Vitamin A is linked mainly with vision and epithelial health. Vitamin C deficiency causes scurvy, not beriberi. Vitamin D deficiency affects calcium absorption and bone health, leading to conditions such as rickets or osteomalacia.
