During project execution, the customer authorizes and funds a scope change which requires a major change in the schedule. The baseline schedule?

A. Is the same since baseline schedules cannot change once the development phase is completed.

B. Is meaningless since every schedule update changes the baseline (i.e., a rubber baseline.)

C. Is amended to reflect the scope change, but the original baseline is still maintained for post project review.

D. Now becomes the new schedule, including the changes, and the original baseline is disregarded.
