Hi,

As the masses are given, you can find the molar mass of each of compound by meare addition. Now u have masses of compounds, you can do the option check.

Do remember that one mole is the mass of compound which constitutes masses of all the individual atoms keeping in mind the no of atoms used in the compound of same type.
