In a recent Automatic Workload Repository (AWR) report for your database, you notice a high number of buffer busy waits. The database consists of locally managed tablespaces with free list managed segments. On further investigation, you find that buffer busy waits is caused by contention on data blocks. Which option would you consider first to decrease the wait event immediately?（）
- A、Decreasing PCTUSED
- B、Decreasing PCTFREE
- C、Increasing the number of DBWN process
- D、Using Automatic Segment Space Management (ASSM)
- E、Increasing db_buffer_cache based on the V$DB_CACHE_ADVICE recommendation
