What is a common purpose of nail enamel remover?

Nail enamel remover is specifically formulated to dissolve nail polish, making option C the correct choice. It typically contains solvents such as acetone or non-acetone ingredients that effectively break down the compounds in nail polish, allowing for easy removal. This process is essential for maintaining nail health and cleanliness, especially for individuals who frequently change their nail colors or designs.

Other options, such as moisturizing the nails, soothing inflammation, or fortifying nail structure, do not align with the primary function of nail enamel remover. While some products might offer additional benefits, the essential characteristic of nail enamel removers is their ability to cleanly and efficiently remove nail polish.
