Which of the following statements best describes the filtering ability of a fine mesh metal lube oil strainer?

Correct Answer: Option D — A 200 wire mesh screen will prevent passage of smaller particles than a 100 wire mesh screen.

Mesh size refers to the number of openings per linear inch. A 200-mesh screen has more wires per inch than a 100-mesh screen, resulting in smaller individual openings. Therefore, a 200-mesh screen is finer and effectively prevents the passage of smaller particles than a 100-mesh screen.
