The correct answer is A . BABOK states that the purpose of Define Future State is to determine the set of necessary conditions to meet the business need . It also defines the goals, objectives, and outcomes that indicate the business need has been satisfied. Since the question mentions understanding the vision, outcomes, and conditions that will enable the enterprise to achieve its objectives, this directly matches the Define Future State task.
Option B is incorrect because Define Change Strategy focuses on identifying the best approach for moving from the current state to the future state. That comes after the future state is clearly understood.
Option C is incorrect because Verify Requirements is concerned with ensuring requirements are of sufficient quality, such as being clear and testable. It does not focus on defining the enterprise vision or future conditions.
Option D is incorrect because Assess Risk evaluates uncertainties and their potential effect on the change, but it does not establish the desired future vision, outcomes, or enabling conditions
