Answer: C - The Business Case must be viable, the project plan adequate, and the strategies appropriate.
Key takeaway: Reviewing the Business Case is simply holding to the principle of Continued Business Justification, and is not just done when authorising a project, but at every stage boundary when authorising the next stage. In addition to this, the project plan must be able to deliver the Business Case as it is described, and the project strategies must support this delivery. If any one of these criteria fails, then approval should not be given until the problems have been rectified. If the Business Case is not valid, then the project may be shut down completely before it has even properly begun.
