The deficiency of which of the following vitamins causes Pellagra?

B3

The correct answer is Option (3)- B3

The deficiency of B3 (Niacin) causes Pellagra.

Explanation:

Pellagra is a nutritional deficiency disease that results from insufficient intake of niacin (vitamin B3) and tryptophan, an amino acid that can be converted into niacin in the body. Niacin is essential for various cellular processes, and its deficiency can lead to a range of symptoms associated with pellagra.

Symptoms of pellagra include skin rashes, diarrhea, dementia, and other neurological symptoms. Niacin is important for the metabolism of carbohydrates and fats, and its deficiency can occur in individuals with a diet lacking in niacin-rich foods or those with conditions that affect niacin absorption or conversion.

The other B vitamins listed—B1 (Thiamine), B5 (Pantothenic Acid), and B2 (Riboflavin)—are associated with different functions in the body, and their deficiencies lead to other specific disorders but not pellagra.
