Explanation/Reference:
Progressive elaboration describes the project management approach of refining requirements and project scope.
C is incorrect. Iterative is not a valid business analysis approach.
A is incorrect. The plan-driven approach defines business analysis activities. This approach is
used to focus on minimizing up-front uncertainty and to ensure that the solution is fully defined before implementation begins in order to maximize control and minimize risk. It is preferred when requirements are effectively defined in advance of implementation.
B is incorrect. Change-driven approaches to business analysis deal with rapid delivery of the
business value. The business value is delivered in short iterations in return for acceptance of a higher degree of uncertainty regarding the overall delivery of the solution.
The change-driven approaches are preferred while taking an exploratory approach for incremental improvement of an existing solution.
