Solution

The correct option is C Assertion is correct but Reason is incorrect
The constituents of petroleum can be separated by fractional distillation as they have different boiling points and are homogeneous. Fractional distillation is a method of separating homogeneous mixtures having different boiling points (generally, when the boiling point difference is less than $25^{o} C$ ).
Therefore, option C is correct.
