A 7-year-old boy from a resettlement colony presents with swollen, bleeding gums, perifollicular hemorrhages over the lower limbs, and corkscrew hair formation. Serum ascorbate is undetectable. The ICMR-NIN 2020 RDA of Vitamin C for an adult Indian male (60 kg) is approximately:

• A 75 mg/day
• B 50 mg/day
• C 40 mg/day ✓
• D 30 mg/day

Explanation

The child has scurvy (Vitamin B deficiency). The ICMR-NIN 2020 RDA for Vitamin B for an adult Indian male is 40 mg/day. This is lower than the earlier 1989 RDA of 60 mg/day. The key discriminating detail is the revised 2020 value; option D (30 mg) is close but incorrect, while 75 mg reflects older recommendations or Western guidelines.
