UPSC 2016 CDS I GK Paper

Rickets is a condition that results in weak or soft bones in children, usually due to inadequate vitamin D (not vitamin A as given in the question). Beriberi is a disease caused by vitamin B1 deficiency, also known as thiamine deficiency. There are two types of the disease – wet beriberi and dry beriberi. Scurvy happens when there is a lack of vitamin C or ascorbic acid. The deficiency leads to symptoms of weakness, anemia, gum disease and skin problems. This is because vitamin C is needed for making collagen, an important component in connective tissues. So, only 2 and 3 are correctly matched.
