Chemistry ma’am · 5 steps
Tie each B vitamin to the body part it fails: riboflavin to lips, thiamine to nerves, pyridoxine to the brain.
- Riboflavin. Riboflavin is vitamin B₂. Its deficiency causes cheilosis, cracks and fissures at the corners of the mouth and lips, so (i) goes with (c).
- Thiamine. Thiamine is vitamin B₁. Its deficiency causes beriberi, which weakens nerves and muscles and causes loss of appetite, so (ii) goes with (a).
- Pyridoxine. Pyridoxine is vitamin B₆. Its deficiency causes convulsions, so (iii) goes with (d).
- Ascorbic acid. Ascorbic acid is vitamin C. Its deficiency causes scurvy, with bleeding gums, so (iv) goes with (b).
- So. The full match is (i)-(c), (ii)-(a), (iii)-(d), (iv)-(b), which is option (c).
The idea to keep. Learn the B vitamins by number with their deficiency: B₁ beriberi, B₂ cheilosis, B₆ convulsions, B₁₂ pernicious anaemia. Vitamin C goes with scurvy.
