Polish remover or alcohol can be used as a:

• A. Nail preparation solution
• B. Top coat
• C. Base coat
• D. Nail bleach

Answer: (A)

Cleaning and dehydrating the nail surface is what a nail preparation step is all about. Using polish remover or alcohol helps remove oils, dirt, and moisture from the natural nail so the next products—like primers, gels, or polish—adhere better and don’t lift later on. This preparatory action is why it’s described as a nail preparation solution.

The other options have different roles: a top coat adds shine and seals the finished look, a base coat creates adhesion and protection under color, and bleach is used to whiten or remove stains. None of those describe the preparatory cleansing/dehydrating function that polish remover or alcohol provides.
