- $>$ 5 ppm, 0.005 ppm
- $>$ 5 ppm, 0.05 ppm
- $<$ 5 ppm, 0.05 ppm
- $<$ 5 ppm, 0.005 ppm
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Clean water has a BOD (Biochemical Oxygen Demand) value of less than 5 ppm. The permissible concentration of cadmium in drinking water is limited to 0.005 ppm to avoid toxicity.
