  2. Bwater at 80°C80 ° C
  3. Cpolluted water
  4. Dwater at 4°C4 ° C

Correct answer

D. water at 4°C4 ° C

Step-by-step solution

On heating concentration of O2{O}_{2} in water decreases. So boiling water and water at 80°C80 ° C having less O2{O}_{2} concentration. Polluted water also having less O2{O}_{2} concentration. So water at 4°C4 ° C is having maximum O2{O}_{2} concentration.
