Filtration

Explanation:

Filtration can be defined as the technique which is used to remove the solute particles or solid dust particles that is suspended in the liquid.

There are various types of filtration techniques available for the filtration of dust particles from oil.

Oil is passed through the filtration membrane, filtration membrane stops the dust particles on the membrane that is equipped to filter smaller particles. The filtered oil is collected after this process.

The correct answer is that Erica will use filtration technique to filter oil.
