The correct answer is C. Specify and Model Requirements and Designs is the task where business analysis information is analyzed, refined, represented, and structured so stakeholders can understand needs and potential solutions. The scenario describes ongoing review and refinement of stakeholder feedback, with a focus on making the information complete and consistent. That aligns directly with specifying and modelling. Option A is incorrect because governance defines decision-making and approval processes. Option B is incorrect because planning the approach is about determining how business analysis work will be performed, not refining stakeholder feedback. Option D is incorrect because prioritization ranks requirements by value, risk, urgency, or dependency. The activity described is analysis and representation, not governance, planning, or ranking.
