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 the statements given above are correct?

The correct answer is A because of the following reasons:

Statement 1 is correct. Vitamin A deficiency leads to Xerophthalmia, a condition where the lachrymal glands fail to produce tears, causing the eyes to become dry.

Statement 2 is correct. Vitamin B1 or Thiamine deficiency causes Beri-beri. This condition can affect the digestive system leading to indigestion and can also impact the cardiovascular system, potentially causing heart enlargement or failure.

Statement 3 is incorrect. While Vitamin C deficiency causes Scurvy, which is primarily characterized by bleeding gums and poor wound healing, muscle pain is not its primary diagnostic symptom in the context of standard nutritional science.

Statement 4 is incorrect. Vitamin D is essential for the absorption of Calcium. Its deficiency leads to decreased absorption of Calcium from the gut, not an increased loss of Calcium in the urine. In fact, Vitamin D deficiency usually results in lower levels of Calcium in the body.

Therefore, only statements 1 and 2 are accurate.
