Under the standards enforced for iodised salt in India, the minimum iodine content that salt must retain at the retail (consumer) level is:
- A At least 30 ppm
- B At least 15 ppm ✓
- C At least 20 ppm
- D At least 50 ppm
Correct answer: B. At least 15 ppm
Explanation
Indian standards require iodised salt to contain not less than 30 ppm iodine at the point of production, allowing for losses during transport and storage so that at least 15 ppm is retained at the consumer level. Choosing 30 ppm reflects the production-level standard rather than the retail-level standard, which is exactly the discrimination this item tests.
