Explanation:

Reverse osmosis is for separating dissolved substances by pressure - difference across a semi - permeable membrane. Osmosis is the movement of solvent molecules across a semi - permeable membrane. Dilution involves adding more solvent. Filtration is a method to separate solid particles from a liquid (or gas) by passing the mixture through a filter medium. To remove fine dust particles suspended in oil, filtration is the most appropriate method.

C. filtration
