Between the Two Levels of Strategy, the Division of Responsibility

Between the two levels of strategy, the division of responsibility is consistent with the following principle:

A) There is no principle but only limited rationality and trial-and-error processes to find the best articulation between these two responsibilities within the firm
B) Corporate level strategy is the domain of top managers, while division managers are in charge of their business level strategies
C) Corporate level strategy is the domain of the parent company, and the business level strategy is handled by the functional department managers
D) Corporate and business level strategies are not any specific organizational level's responsibility because of the principle of maximum delegation and decentralization
