In a project schedule you create in Microsoft Office Project Standard 2007, you transfer a resource from Task A, a partially completed task, to Task B, a more urgent task. You reschedule the remaining Task A work to a later date, and save the project schedule. The management team reviews and reprioritizes the tasks, so that Task A is now more important than Task B. You need to change the rescheduled Task A work so that it reflects the situation before the resource was transferred. What should you do?

A.
Invoke the Undo command.

B.
In the Gantt Chart view, update the resources for the remaining portions of the task.

C.
Change the calculation options for moving the end of the remaining work to after the status date.

D.
Remove the task split by adjusting the Gantt bar so that the actual and remaining portions of the task are adjacent.
