Aqueous solutions is a kind of solution where in the solvent is water. It is commonly labelled as (aq) after the compound. For example NaCl (aq). This also means that the solutes is dissolved in water.
There are kinds of aqueous solutions: ionic and molecular. Ionic aqueous solution is when the solute is an ionic compound or forms/splits into ions within the solution. Molecular on the other hand do not dissociate into ions in the solution.
In your question, sucrose or C12H22O11 do not form ions when in the solution. Therefore it is molecular.
hope this helps :)
