The mixture of kerosene and diesel oil can be separated by distillation.

Here's the step-by-step process:

1. The mixture is heated: Both kerosene and diesel oil are hydrocarbons, but they have different boiling points. When the mixture is heated, the substance with the lower boiling point will start to vaporize first.

2. The vapor is collected: The vapor produced by heating is collected and moved into a condensing apparatus.

3. The vapor is cooled and condenses: In the condensing apparatus, the vapor is cooled down. As it cools, it changes back into a liquid state. This liquid is then collected in a separate container.

4. The process is repeated if necessary: If there are still impurities or if the substances have very close boiling points, the process may need to be repeated.

So, the correct answer is B. Distillation.
