I had to look at the images to know what options I had. Sugar is soluble in water, so it has a saturation point at which it precipitates as a solid into a solution containing a large amount of sugar. If the amount is small, the sugar dissolves completely and no particles are observed in the solution.
All solutions are mixtures of two or more substances, but unless the mixture has a homogeneous distribution of solutes in the solvent, then the mixture is not a solution. Therefore, all mixtures are not solutions.
