In your production database, users report that they are unable to generate reports on an important table because it does not contain any data. While investigating the reason, you realize that another user executed the TRUNCATE TABLE command, which accidentally caused the data to be lost. Now you want to recover the lost data of the table without affecting objects in other schemas.
Which method must you use to recover the lost data?（）

B. Recommending optimization of materialized views
C. Checking query objects for missing and stale statistics

B. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are set
C. The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are set
D. Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program Global Area (PGA) will be distributed at startup

A. Set MEMORY_TARGET to zero
B. Set the STATISTICS_LEVEL parameter to BASIC
C. Set the WORKAREA_SIZE_POLICY parameter to MANUAL
