Answer:
The correct answer is: "D. Both external and internal".
Explanation:
The only possible answer to fill in the space is letter D because it is reasonable to think that a company should focus both on external and internal values for customers in order to make it grow for both parts. As it is an event management company, it is very important to highligh the external demands and how they come and go with clients, agencies, and subsidiaries, while the company must take care of their internal customers who are more responsable for maintaining their strategy going on properly.
