[单选题] Your system has been upgraded from Oracle Database 10g to Oracle Database 11g. You imported SQL Tuning Sets (STS) from the previous version. After changing the OPTIMIZER_FEATURE_ENABLE parameter to 10.2.0.4 and running the SQL Performance Analyzer, you observed performance regression for a few SQL statements. What would you do with these SQL statements?（）

A、Set OPTIMIZER_USE_PLAN_BASELINES to FALSE to prevent the use of regressed plans. B、Capture the plans from the previous version using STS and then load them into the stored outline. C、Capture the plans from the previous version using STS and then load them into SQL Management Base (SMB). D、Set OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES to FALSE to prevent the plans from being loaded to the SQL plan baseline.
