The correct answer is option A
Solution can be defined as the mixture of solute and solvent in which the solute is generally in the form of solid and the solvent is in the form of liquid.
The solution once made by the mixture of solute and solvent is a homogeneous solution which means the solute and the solvent cannot be separated.
So, the sand in water can be easily separated from each other because they do not mix together to form a solution.
