Solution

The correct option is C Assertion is correct but Reason is incorrect
The molecular formula shows the exact number of different types of atoms present in a molecule of a compound. The molecular formula can be obtained directly from an empirical formula which represents the simplest whole number ratio of various atoms present in a compound if the $n$ factor is known.
i.e. molecular formula = $n \times$ Empirical formula
where $n = \frac{m o l a r m a s s}{E m p i r i c a l m a s s}$
An assertion is correct but Reason is incorrect.
Hence, option $C$ is correct.
