Answer: C. exporting
Step-by-step explanation:
As many services have to be produced where they are sold, Exporting is not very ideal in the Service industry even if it might work here and there.
Exporting is a form of FDI that means sending the good in question to another country and this is not ideal when services are needed.
For instance, you need your hair cut in Maine but Maine uses exported Barbers from Mexico City, the logistics of such a business are to understate it, untenable. The barber should be in Maine.
