Answer:
The best answer is c. both of them.
Step-by-step explanation:
Both the dentist and the dental auxiliary may be liable for the actions of the dental auxiliary. In many jurisdictions, dentists are considered responsible for the actions of their dental auxiliaries, such as dental assistants or dental hygienists, who work under their supervision. The dentist is responsible for properly training and supervising the dental auxiliary to ensure they provide safe and competent care to patients. If the dental auxiliary's actions result in harm or negligence, both the dental auxiliary and the supervising dentist may be held liable for any damages or legal consequences.
