It's unchanged, because molarity is nothing but the number of moles of solute present in a solution, the solution contains both solute and solvent so when the solvent get evaporate the molarity of solvent get decreased but the molarity of solute remains constant but it's getting concentrate.

Molarity=no. Of moles of solute/one liter of solution.
In evaporation, we increase the concentration of solute (sugar concentration) means we evaporate (decrease) the aqueous solution (water) then the denominator in molarity decreases therefore the molarity increase.

In a solution we have both water and solute. In the evaporation process solute doesn't evaporate that means solvent will evaporate. So the total volume of the solution will decrease. When the solution volume decreases then molarity will increase.

The evaporation of an aqueous sugar solution increases its molarity because the water is being removed, leaving behind a higher concentration of sugar in the remaining solution.

The right answer should be option B.

Yes, the Molarity should be Increase.

Molarity increases.

Molarity should increase because due to evaporation the concentration of sugar increases in water which hence increases its molarity.
