UPSC 2004: Consider the following statements: 1. Non-function of lachrymal gland is an important symptom of deficiency of Vitamin A. 2. Deficiency of Vitamin B1 can lead to indigestion and heart enlargement. 3. Vitamin C deficiency can lead to pain in the muscles. 4. Deficiency of Vitamin D causes increased loss of Ca++ in urine. Which of these statements given above are correct?

Only statements 1 and 2 are accepted by standard texts and the official key: Vitamin A deficiency leads to xerophthalmia involving the lachrymal glands, and thiamine (B₁) deficiency causes indigestion and cardiac enlargement (wet beriberi). Muscle pain is not a primary diagnostic sign of vitamin C deficiency, and vitamin D lack lowers—not raises—urinary calcium because secondary hyperparathyroidism conserves Ca²⁺. Thus only 1 & 2 are correct. ([licchavilyceum.com](https://licchavilyceum.com/upsc-civil-services-prelims-2004-solved-question-paper/?utm_source=openai))
