Solution

The correct option is C Cooling water
The water purification methods are:
  • Filtration: In this process, water is made free from impurities using a filter.
  • Boiling: Boiling kills the germs present in the water and makes it safe for drinking.
  • Chlorination: A chlorine tablet or bleaching powder is added to water to make it germ free.
