Correct Answer: Option (A) — 1 and 2 only

Concept & Option Breakdown

Standard Reference Verified
  • Pair 1 is correctly matched: Scurvy is caused by Vitamin C (ascorbic acid) deficiency, resulting in bleeding gums and defective collagen synthesis.
  • Pair 2 is correctly matched: Rickets is caused by Vitamin D deficiency, causing soft and weak bones in children (and osteomalacia in adults).
  • Pair 3 is incorrectly matched: Night blindness is caused by Vitamin A deficiency (retinol), not Vitamin E. Vitamin E deficiency causes hemolytic anemia and neurological dysfunctions.
