Riboflavin deficiency causes which of the following diseases ?
- (a)Pellagra
- (b)Scurvy
- (c)Beri Beri
- (d)Cheilosis
Correct — D, Cheilosis. Riboflavin (Vitamin B2) deficiency (ariboflavinosis) classically produces cheilosis — cracking and fissuring at the corners of the mouth and lips (angular stomatitis) — along with glossitis (inflamed, magenta tongue) and seborrhoeic dermatitis. So the deficiency disease paired with riboflavin is cheilosis.
- (a)Pellagra — Pellagra is caused by a deficiency of niacin (Vitamin B3 / nicotinic acid), marked by the '3 Ds': dermatitis, diarrhoea and dementia — not by riboflavin deficiency.
- (b)Scurvy — Scurvy is caused by a deficiency of Vitamin C (ascorbic acid): bleeding/spongy gums, poor wound healing and swollen joints — a different vitamin.
- (c)Beri Beri — Beri-beri is caused by a deficiency of thiamine (Vitamin B1), producing nerve (dry) and cardiac (wet) manifestations — not riboflavin deficiency.
Each water-soluble B-complex vitamin and Vitamin C has a signature deficiency disease. Riboflavin (B2) → cheilosis / angular stomatitis / glossitis; thiamine (B1) → beri-beri; niacin (B3) → pellagra; ascorbic acid (C) → scurvy. Matching each vitamin to its deficiency disorder is a standard science recall.
All four options are genuine deficiency diseases, so the question is purely a vitamin↔disease pairing. Anchor riboflavin/B2 → cheilosis, then eliminate the B1 (beri-beri), B3 (pellagra) and C (scurvy) pairings.
- Riboflavin = Vitamin B2; deficiency (ariboflavinosis) → cheilosis, angular stomatitis, glossitis
- Thiamine (Vitamin B1) deficiency → beri-beri
- Niacin (Vitamin B3) deficiency → pellagra (the '3 Ds')
- Vitamin C (ascorbic acid) deficiency → scurvy
Riboflavin (B2) deficiency → cheilosis; the three distractors pair with B1, B3 and Vitamin C.
- Mixing up the B-vitamins — B1 (beri-beri) vs B2 (cheilosis) vs B3 (pellagra)
- Assuming any mouth or skin lesion is a sign of scurvy
As a direct vitamin↔deficiency-disease match, or as a 'Match List' / 'correctly matched pair' item.
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 these statements given above are correct?
- (a) 1 and 2
- (b) 2, 3 and 4
- (c) 1, 3 and 4
- (d) 1, 2, 3 and 4
Answer(a) 1 and 2
Same concept — pairing vitamin deficiencies (A, B1, C, D) with their clinical effects; riboflavin (B2) belongs to the same vitamin-deficiency framework.
The nutritional deficiency condition that needs to be given top priority for remedial action in India today is
- (a) Scurvy
- (b) Rickets
- (c) Xerophthalmia
- (d) Pellagra
Answer(c) Xerophthalmia
Same concept — a vitamin/nutritional deficiency disease (answer Xerophthalmia = Vitamin A deficiency), the same disease-from-deficiency theme as riboflavin→cheilosis.

Deficiency of which vitamin causes pellagra?
- (a)Vitamin B1
- (b)Vitamin B2
- (c)Vitamin B3 (niacin)
- (d)Vitamin C
Answer(c) Vitamin B3 (niacin) — pellagra shows the '3 Ds': dermatitis, diarrhoea, dementia.
