C i incorect beacuse: When you execute the DBMS_LOGSTDBY.BUILDprocedure, the LogMiner dictionary is built and supplemental logging is automatically enabled for logging primary key and unique key columns. Supplemental logging ensures that each update contains enough information to logically identify the affected row.
