Answer:
Senior executives
Step-by-step explanation:
Senior executives are responsible for an organization's strategic plan because they have the highest level of decision-making authority in the organization. They are responsible for setting the overall direction and long-term goals of the organization. They have a broad view of the organization's strengths, weaknesses, opportunities, and threats, and they are in the best position to make decisions that will help the organization achieve its strategic objectives. They also have the authority to allocate resources and make major decisions that impact the entire organization, which makes them the most suitable for developing and implementing a strategic plan.
