The correct answer is A . BABOK explains that when planning the business analysis approach, the selected approach should fit the change strategy, delivery method, timing, and formality needs of the initiative.
Predictive approaches typically involve more formal documentation and upfront planning and are best suited where requirements are more defined, constrained, or mandatory. A business case's problem statement that emphasizes specific, time-sensitive, and mandatory requirements most directly supports choosing a predictive approach.
Option B is incorrect because market analysis may help justify whether an initiative is worthwhile, but it does not most directly determine whether a predictive approach is the right delivery/analysis approach.
Option C is incorrect because the author's preferences or biases are not the BABOK basis for selecting an approach. The approach should be based on initiative context and stakeholder needs, not on who wrote the document.
Option D is also incorrect because cost-benefit information is important for investment decisions, but it does not most directly indicate whether the work should be handled using a predictive rather than adaptive approach.
