Correct Answer: Reverse Osmosis
Solution : The correct answer is Reverse Osmosis.
Reverse osmosis (RO) is a water purification process that uses a semipermeable membrane to remove impurities, contaminants and minerals from water. In reverse osmosis, water is forced through a membrane that allows water molecules to pass through while blocking the passage of larger molecules, contaminants and ions. Pressure is applied to push water through the membrane, leaving behind impurities.
