-
A.
Vacuum distillation
-
B.
Zonal distillation
-
C.
Fractional distillation
-
D.
Simple distillation
Correct Answer:
C. Fractional distillation
Explanation:
Fractional distillation is the technique used to separate various components of crude oil, such as petrol, diesel, and kerosene. This process relies on the different boiling points of the hydrocarbons within petroleum. When crude oil is heated in a fractionating column, the different substances vaporize and then condense at specific levels based on their individual boiling ranges, allowing them to be collected separately.
