The correct method to separate a mixture of kerosene and petrol is fractional distillation. Both kerosene and petrol are miscible liquids with different boiling points (petrol boils roughly between 40°C and 205°C, kerosene between 175°C and 325°C). Fractional distillation is used to separate miscible liquids that have close boiling points.
Fractional distillation is a technique used to separate miscible liquids with different boiling points, involving repeated vaporization and condensation steps within a fractionating column.
