1 mole can be written many different ways.  Converting a mole to atoms would require you to multiply the number of moles by (6*10^23), so b is out.  Converting moles to Liters would require multiplying the number of moles by 22.4, so a is out.  Converting moles to grams would require multiplying the number of moles by the molar mass of the element/compound.  The molar mass of Pb (Lead) is 207, so e is out.  The molar mass of SO2 is 32 + 32 = 64, so c is out.  That only leaves d.  In order to prove this, take the molar mass of H2O (which is 16 +1 +1 = 18) and multiply it by 1.  The number you get from this is 18, which is not 36, so your final answer is D.
