Answer:
The correct answer is A, as the statement is true.
Step-by-step explanation:
Indeed, the fact that pharmacy chains such as Walgreens or CVS have begun to provide medical services, being in principle simple pharmacy chains, is an example of how services begin to centralize and become more accessible and faster. Thus, services that previously required an appointment with a doctor today can be accessed by simply visiting a local of these chains. In this way, times are reduced and services are provided at a low cost, in the same way that fast food chains reduce time and costs in their services.
