Correct Answer: B
When a project encounters a risk that was not fully anticipated, and the project manager has developed a new response that deviates from the original plan, it is essential to obtain management approval before proceeding.
This ensures that the new approach is aligned with the project's objectives and that management is aware of the changes being made to the risk response plan. The PMBOK Guide highlights the importance of involving project stakeholders, particularly management, when significant changes are proposed1. This is also supported by best practices in business analysis, which advocate for stakeholder engagement and approval in the decision-making process to address risks effectively2.
