Solution
The correct option is A Filtration
Filteration is a physical method that can only separate the pathogens and other contaminants from water but cannot kill microorganism.
Boiling kills all the pathogens at boiling temperature.
Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules.
Distillation relies on evaporation to purify water. Contaminated water is heated to form steam. The boiling process kills microorganisms such as bacteria and some viruses.
