Why the answer is B, and why the others tempt you.
Coating metal surfaces with oil or grease creates a barrier that prevents moisture and oxygen from reaching the metal, thereby preventing oxidation (rusting). Storing in a damp place accelerates rusting, daily sharpening causes unnecessary wear, and leaving tools wet in the sun still allows rust to form.
