One major component that assists the filtering of oil is the

• A. Strainers
• B. Gaskets
• C. Pistons
• D. Bearings

Answer: (A)

Filtering oil relies on devices that remove contaminants from the circulating oil. A strainer acts as a screen that catches dirt and metal particles as oil flows from the sump toward the pump, helping protect the pump, bearings, and other components from damage. The other options serve different roles: gaskets seal joints and don’t filter, pistons are moving components, and bearings are the parts being lubricated rather than filtering devices. So the strainer is the component that directly assists filtering.
