Explanation
Requirements are based on stakeholders' needs, wants, and expectations. This is why it's important to identify stakeholders and requirements gathering processes early in the project to quickly and accurately capture requirements.
Answer D is incorrect. This is not a valid answer to the question as not all requirements gathering are solutions-driven, but could be just a study.
Answer B is incorrect. The risk and reward solution is always considered, but requirements are based on stakeholders' needs, wants, and expectations.
Answer C is incorrect. The change-driven approach isn't a valid answer for this QUESTION.

Explanation
Progressive elaboration describes the project management approach of refining requirements and project scope.
Answer C is incorrect. Iterative is not a valid business analysis approach.
Answer 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.
Answer 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.

Explanation
Effective business analysis practices can reduce the amount of change in a project, but it cannot eliminate the amount of changes entirely.
Answer D is incorrect. This isn't a valid statement as business analysis practices cannot eliminate the need for change in requirements.
Answer C is incorrect. While this may be true in some instances, it's not true for all areas of requirements change.
Answer B is incorrect. This isn't a valid statement to the QUESTION. All changes and requirements must be documented.

Explanation
For requirements to be approved, they must support the solution scope. The solution scope defines what's in and out of the range of requirements for business analysis activities.
Answer B is incorrect. A technical review doesn't approve requirements; the solution scope defines what's approved based on what's in alignment with the scope.
Answer C is incorrect. The requirements management plan doesn't affect the requirements that are or are not approved.
Answer D is incorrect. While this statement may be somewhat true, it doesn't define how requirements are approved before their governance.
