Sorry this comment is for Q. 150
C
Little tricky question, DBUA runs Pre-Upgrade tool as one of its steps. However Oracle recommends to run the tool before starting DBUA to run the tool ahead of time in order to analyze the database and take actions that can decrease downtime for upgrading.
BTW expl. link leads to 11g not 12c, there is the correct one:
http://docs.oracle.com/database/121/UPGRD/upgrade.htm#i1011482
C is correct one.
