You are a project manager for an organization that uses Project Server 2013. You have the appropriate permissions to set all baselines. Your project experiences a scope change, which requires you to add tasks to the end of the schedule. You need to retain historical information for both completed and in-progress tasks but create a baseline that includes the newly-selected tasks. You check out your schedule in Project Web App (PWA) for editing and select the newly-added tasks. What should you do next?
A. Set an interim plan.
B. Use an unused baseline to set a new baseline.
C. Clear the baseline and then set a baseline for the entire project.
D. Set a baseline for only the selected tasks.
