D. The commander in chief role addresses major problems, while the chief of state role is mostly symbolic.
Explanation:
The roles of commander in chief and chief of state are significantly different. The commander in chief is the ultimate authority of all United States Armed Forces. This enables him to make important decisions during times of crises, although the specific level of this power has varied throughout history. On the other hand, the chief of state role is mostly a symbolic position. It identifies the President as the head of the government and symbol of all the people.
