  • @Nishant-Thakre The vapour pressure of the pure solvent is more than that of yhe solution as on addition of non volatile solute to a pure volatile solvent the vapour pressure decreases...furthermore some amount of condensation of vapours of the solvent also takes place ...but since both the beakers are placed in the same container ,we can assume that the volume addition due to condensation for each beaker is nearly the same ...but since rate of evaporation is more for the beaker containing pure solvent ....option A is correct
