Which of the following is a step in a basic manicure?

The step involving soaking, trimming, and shaping the nails is fundamental to a basic manicure as it focuses on the essential preparation and care of the nails. Soaking helps to soften the cuticles and the nails, making it easier to push back the cuticles and trim any excess skin. Trimming the nails ensures they are of a desirable length, while shaping the nails gives them a neat appearance and helps to avoid breakage or uneven growth. This comprehensive approach not only enhances the aesthetic appeal but also contributes to nail health, making these steps integral to the overall manicure process.

While removing nail polish with acetone, applying moisturizing cream, and using a UV lamp to dry the nails are also related to nail care and may occur in a salon setting, they do not represent the core steps that constitute the basic structure of a traditional manicure.
