Hint: Limit of vision of human naked eye is upto \[10\mu m\], we cannot see further smaller particles. If the solution contains the particles that are in the range of size of naked human eye’s vision limit, then we can see them.

Complete answer:
True solutions are those who have solute particles completely dissolved in the solution. In true solutions the particle sizes of solute are around 1 nm or \[{10^{ - 9}}m\] .
A human naked eye cannot see particles smaller than \[10\mu m\] means \[{10^{ - 5}}m\].
So, as the particle size of the true solution is much smaller than the limit of naked human eye’s vision, hence we cannot see them. So, the statement in the question is false.

So, the correct answer is (B) False.

Additional Information True solution is always homogeneous and has a particle size around 1nm.
> The particles that are dissolved in the solution are called solute particles. The medium or liquid that dissolves the solute is called solvent and the whole system of solvent and solute dissolved in it is called solution.
> Mixtures can be either homogeneous or heterogeneous but solutions are always homogeneous.
> All homogenous mixtures are not solutions but all solutions are homogeneous mixtures.

Note: When solute is not dissolved in the solute completely, the solution can not be regarded as a true solution. In the true solution solute dissolves into solvent completely.
