Solution

The fraction distillation process is used to separate different liquids from petroleum. A distillation tower is used to perform this operation in which different exit holes are present.
The liquids can be obtained depending upon the boiling temperatures of the liquids. The order of liquids obtained according to the boiling temperatures is shown below:
S. No. Liquid Temperature range
1. Petrol 40℃ to 170℃
2. Naphtha 60℃ to 110℃
3. Kerosene 170℃ to 250℃
4. Diesel 250℃ to 350℃
5. Fuel oil 350℃ to 400℃

Liquid A falls in the first range.
Liquid B falls in the fourth range.
Liquid C falls in the fifth range.
Liquid D falls in the fourth range.

Thus, the order of obtaining the liquids is as follows:
A, B, D, C
