Correct Answer
(B) Riboflavin
Solution & Explanation
\textbf{Answer:} (B) Cheilosis results from deficiency of riboflavin (vitamin B2). \textbf{Solution:} Cheilosis — cracking and inflammation at the corners of the mouth and lips — is the classic deficiency symptom of vitamin B2 (riboflavin), a water-soluble vitamin. Pyridoxamine is a form of vitamin B6, thiamine is B1 (deficiency causes beri-beri), and nicotinamide is the amide of niacin/B3 (deficiency causes pellagra). Hence option B is correct.
