Final answer:
Making impressions for study casts not intended for fabricating dental devices falls under general supervision, allowing dental assistants to perform these tasks without the dentist's physical presence.
Explanation:
In dental practice settings, the type of supervision under which certain tasks are performed can vary. Typically, general supervision allows dental assistants to perform specific tasks without the dentist being physically present, provided these tasks are within their scope of practice and the dentist has authorized the procedures to be carried out. Given this information, the correct answer is c) General supervision. This level of supervision is ideal for tasks like taking impressions for study casts, which do not directly involve the fabrication of dental devices or interventions.
