What is the licensee responsible for verifying according to compliance with applicable law?

The correct choice emphasizes the licensee's responsibility to ensure that the salon or school is operating with a current license, which is essential for legal compliance. Keeping the establishment's licensing up to date demonstrates adherence to state regulations and consumer protection laws. This responsibility not only ensures that the business can legally operate but also protects clients, employees, and the business itself from potential legal issues that could arise from operating without the necessary licenses.

While it is important for clients to be satisfied, products used to be safe, and staff to be properly trained, these factors do not directly pertain to the legal compliance aspect of licensing. Ensuring that the salon or school maintains a valid license is a foundational requirement that supports all other areas of operational integrity within the nail technician profession.
