A base coat, option A, is used to protect the nails from staining and provides a smoother surface for the nail polish to adhere to, but it will not prevent chipping. Trimming the nails, option B, can help prevent breakage and tears, but it will not prevent chipping of the nail polish. Option D, using acetone first, is actually damaging to the nails and should not be used. The best way to prevent chipping of nail polish is by applying a top coat, option C. This acts as a protective layer, sealing in the nail polish color and providing a glossy finish.
