Answer:

It forms a solution.

Explanation:

A pure substance is when only one type of atom or molecule is present. In this case the substance contains two different molecules; sugar and water, assuming sugar is all one type (e.g. glucose) and there are no contaminants in the water or sugar before combining the two.

Dissolving the sugar in the water makes a homogenous mixture and once dissolved a solution is made by the combination of a solute (sugar) and solvent (water).
