The sponsor requests new features when the project is 95% complete and insists continued support depends on adding them. What should the project manager do?

The project manager should assess the impact of the new features and refer them to the change control board (CCB). This follows the established change management process, ensuring that all proposed changes are formally reviewed, approved, or rejected based on their impact on scope, schedule, cost, quality, and resources. Implementing the features without assessment or CCB approval (Option A) bypasses critical controls and could negatively affect the project. Rejecting the features outright (Option B) is premature without a formal assessment and CCB review. Adding the features to avoid losing support (Option D) is a reactive decision that prioritizes stakeholder appeasement over proper project governance and could lead to scope creep and project failure.
