Answer:
Carter is using the B. middle-of-the-road style of leadership.
Step-by-step explanation:
Blake and Mouton developed a Managerial Grid in which various leadership styles are explained. These, as shown on the picture below, are rated according to concern for people and concern for task.
The middle-of-the-road style is at the center because it creates a balance between tasks and individuals.
In this case, Carter meets his employees halfway, being strict but granting them a month off every year. His concern for his employees is medium, as well as his concern for tasks.
