Which two statements give a correct inference based on the DB Time and DB CPU in the Time Model Statistics?

You generate an AWR Compare Periods Report for two consecutive time periods as a routine activity to monitor your database performance.View the Exhibit and examine the partial details of the Time Model Statistics generated in the report.

B.
A change to the database configuration reduced the % DB time for transactions.

C.
More of DB Time was consumed by background processes in the first time period.

D.
A reduction in Hard Parse activity resulted in a reduction of DB CPU Time (in seconds).

E.
More transactions were processed in the first time period based on the DB Time values.
