After stakeholders in a company's sales department examined all the deliverables, they state that there has been a change in the company strategy. Therefore, important changes must be made to the requirements. The project manager believes that these changes make the deliverables unusable. What should the project manager do? 

Evaluate and incorporate the changes to the project management plan to start executing them. 

Evaluate the impact on the project, coordinate with the sponsor and close the project. 

Request that stakeholders specify the new requirements and present them to the change control board (CCB). 

Request the details about the new requirements, evaluate them with the project team, and recommend whether to continue or close the project.
