In which of the following mixtures, components cannot be separated by filtration?

True solution

The correct answer is option 1.  True solution.

A true solution is a homogeneous mixture.

The solute particles are uniformly distributed throughout the mixture i.e., the same composition throughout the mixture.

The solute particles cannot be separated from the mixture by the process of filtration.

The solute particles do not settle down when left undisturbed, that is, a solution is stable.
