• A 0.5 mg/L
• B 1.0 mg/L
• C 1.5 mg/L ✓
• D 2.0 mg/L

Explanation

As per BIS (IS 10500:2012), the acceptable limit of fluoride in drinking water is 1.0 mg/L, with 1.5 mg/L being the permissible limit in the absence of an alternate source. Under NPPCF, water with fluoride >1.5 mg/L is considered unsafe and requires defluoridation. The programme focuses on endemic districts for surveillance and mitigation.
