The answer is D.
Step-by-step explanation:
Strategy is set of goals. Strategic action can be done but not quickly. Tactics are the specific actions one undertake to actualize the strategy.
Also, Strategy defines long-term goals and how you're planning to achieve them. Mission statement, vision statement are all part of a firm's strategy. For example, entering a new foreign market is a strategic action/plan. Tactics are specific and are short-term goals.
