Synchronous Ethernet (SyncE) slave nodes while maintaining traceability to the DS1 source?
A. Enable "ql-override prs" on the BITS reference
B. Enable "ql-override prs" on the master's SyncE ports
C. Enable "ql-selection prs" on the BITS reference
D. Set the master router to choose its source by quality level
