Crystals are not lesser because by dissolved and liquid is evaporated crystal remains same.

Molarity = Number of moles of solute/volume of solution.
Due to evaporation, solute crystals lessen. So volume of solution also reduces. So, no of moles of solute and volume of solution both reduces hence Molarity remains unchanged because molarity pertains to no of moles of solute to particular vol of solution.

I agree with other comments. Molarity must increase.

There must be an error with the choices itself. Answer is B but due to some reasons, the letter seem to be moved and adjusted.

Molarity must increase because solute sugar is not evaporated in this evaporation process and volume of the solvent is decreasing that's why molarity must increases.

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