Answer: A. Who can legally call themselves a medical practitioner and offer patient services?
Step-by-step explanation:
The research paper relates to regulation which means that it falls into the realm of government and what is legal or illegal. This rules out options B and C.
Going further, option D is ruled out as well because it does not speak much to regulation.
The correct option must be option A because it deals with what is legally acceptable and what isn't with regards to offering patient services which is what alternative health clinics do.
