Answer:
D) inseparability.
Step-by-step explanation:
In the marketing terms inseparability refers to the situation where the service is not different from the service provider. As basically for a consumer there is no difference in the service provided and the service provider.
It concludes that there is no difference in the production of a service and rendering of a service.
Here in the given instance the doctor might suit Sean for some other cause but he is not ready to visit the doctor again as he has concluded that his service in this particular case and that in any other case would not be different as he is not a good doctor.
Thus, there is no difference in his eyes in product and service.
