Explanation
The best choice is to do at least one assessment or multiple assessments to compare the solutions.
Answer D is incorrect. There can be multiple solutions to a business need, so the business analyst may need to
perform multiple assessments.
Answer C is incorrect. There's not a restriction of just one assessment per solution, as multiple assessments
can be completed.
