The correct answer is A. Kerosene, Gasoline, Diesel.

Here's why:

The refining of crude oil involves heating the oil and collecting the different substances that boil off at different temperatures. This process is known as fractional distillation.

1. Kerosene: It has a boiling point range of 150 to 275 degrees Celsius. It is the first to appear as the temperature increases.

2. Gasoline: It has a boiling point range of 30 to 200 degrees Celsius. However, in the refining process, it is collected after kerosene because it is lighter and rises higher in the distillation column.

3. Diesel: It has a boiling point range of 200 to 350 degrees Celsius. It is collected after gasoline because it is heavier and does not rise as high in the distillation column.

So, the order of appearance with increasing temperature during the refining of crude oil is Kerosene, Gasoline, Diesel.
