Which common principle do painting and oiling use to prevent rusting?

Answer and explanation

Correct answer: Isolating the iron surface from air and moisture

Rusting requires iron to be in contact with oxygen and water or moisture. Paint and oil form a protective coating on the iron surface, so air and moisture cannot reach the metal. Therefore, option A is correct. Raising the temperature does not create a barrier between iron and oxygen or moisture.
