After analyzing a set of requirements documents, it is determined that the requirements are not yet ready for peer review. This was most likely caused by:
A. some requirements having not yet been discussed in a work group session.
B. the requirements documents having not yet received sign-off from the sponsor.
C. the requirements not providing all of the information needed to define the work.
D. the requirements’ reference codes not tracing to the attribute numbers in the work breakdown structure.
