Solution

The correct option is C Assertion is incorrect but Reason is correct
One mole of $S O_{2}$ contains the same number of molecules as that present in one mole of $O_{2}$ . This is because the one mole of any substance contains Avogadro's number of molecules.

Molecular weight of $S O_{2}$ is 64 g/mole. It is double to that of $O_{2}$ . The molecular weight of $O_{2}$ is 32 g/mole.

Hence, option $C$ is correct.
