Which statement is correct with respect to Pellagra?

Correct option is B

Pellagra is caused by a deficiency of Niacin (Vitamin B3) and is commonly associated with maize-based diets.
· (a) Occurs due to pyridine deficiency – Incorrect, as pellagra is due to Niacin (Vitamin B3) deficiency, not pyridine.
· (b) Occurs with diet chiefly on maize – Correct, as maize lacks sufficient niacin, and its overconsumption can lead to pellagra.
· (c) Night blindness is an important feature – Incorrect, as night blindness is a symptom of Vitamin A deficiency, not pellagra.
· (d) Causes a high risk of heart attack – Incorrect, as pellagra primarily affects the skin, digestive system, and nervous system, not the cardiovascular system.
