A water sample is analysed and found to have concentration of Zn $$= 5.0\ \text{g m}^{-3}$$, Fe $$= 0.5\ \mu\text{g mL}^{-1}$$, Mn $$= 0.05$$ ppm and Cd $$= 0.005$$ ppb. The maximum prescribed concentration of metals in drinking water in $$\text{mg dm}^{-3}$$ is Zn $$= 5.0$$, Fe $$= 0.2$$, Mn $$= 0.05$$ and Cd $$= 0.005$$. Identify the correct statement about the sample of water

A

The water sample is having excess of Zn than the maximum prescribed concentration.

B

The water sample is having lower concentration of Mn and Cd than the maximum prescribed concentration.

C

The water sample is potable (suitable for drinking).

D

The concentration of Fe is 0.5 ppm.
