Detailed explanation-1: -Pure water has the highest concentration of water molecules. Therefore, it has the highest water potential. When some solute is dissolved in water, the water potential of pure water decreases.

Detailed explanation-2: -A hypertonic solution has lower water potential. A hypotonic solution has higher water potential.

Detailed explanation-3: -The greatest amount of water potential that any volume of water has when standard atmospheric pressure is applied to that volume, which is defined as 0. This is referred to as the water potential of distilled water. As a result, distilled water has the greatest ability to move and hence displace other items.
