Pellagra is a disease that occurs due to the deficiency of a specific nutrient. Option 1, ascorbic acid or vitamin C, is not related to pellagra. Option 2, folic acid or vitamin B9, is also not associated with pellagra. Option 3, nicotinic acid or niacin, is the correct answer as it is directly linked to pellagra. A deficiency of nicotinic acid can lead to the development of pellagra. Option 4, pantothenic acid or vitamin B5, is incorrect. While pantothenic acid is an essential nutrient, its deficiency does not cause pellagra. Therefore, for the disease pellagra, the correct answer is option 3, nicotinic acid or niacin.
