From the V$SESSION_LONGOPS view， you find that some of the database users have longrunning queries that consume a lot of CPU time. This causes performance problems for other users in the database， who have much shorter queries.
You would like to make sure that the users with large queries do not use all the CPU time， but you still do not want to terminate them with an error message. Which method would you follow to achieve this？（）

A.set the CPU time per call in the users profile
B.set the CPU time per session in the users profiles
C.set the CPU levels for the users’ group using Resource Manager
D.set the TIMED_STATISTICS parameter to TRUE in the parameter file
