E: You can perform all ALTER PLUGGABLE DATABASE tasks by connecting to a PDB and running the corresponding ALTER DATABASE statement. This functionality is provided to maintain backward compatibility for applications that have been migrated to a CDB environment.
AG: When you issue an ALTER PLUGGABLE DATABASE OPEN statement, READ
WRITE is the default unless a PDB being opened belongs to a CDB that is used as a physical standby database, in which case READ ONLY is the default.
You can specify which PDBs to modify in the following ways:
List one or more PDBs.
Specify ALL to modify all of the PDBs.
Specify ALL EXCEPT to modify all of the PDBs, except for the PDBs listed.

C (not D): CONS_VPD_AUTO
Used to indicate to copy VPD policies automatically
* DBMS_RLS.ADD_POLICY
/ The DBMS_RLS package contains the fine-grained access control administrative interface, which is used to implement Virtual Private Database (VPD).DBMS_RLS is available with the Enterprise Edition only.
Note:
* CONS_USE_PK and CONS_USE_ROWID are constants usedas input to the
"options_flag" parameter in both the START_REDEF_TABLE Procedure and
CAN_REDEF_TABLE Procedure. CONS_USE_ROWID is used to indicate that the
redefinition should be done using rowids whileCONS_USE_PK implies that the redefinition should be done using primary keys or pseudo-primary keys (which are unique keys with all component columns having NOT NULL constraints).
* DBMS_REDEFINITION.START_REDEF_TABLE
To achieve online redefinition, incrementally maintainable local materialized views are used. These logs keep track of the changes to the master tables and are used by the materialized views during refresh synchronization.
* START_REDEF_TABLE Procedure
Prior to calling this procedure, you must manually create an empty interim table (in the sameschema as the table to be redefined) with the desired attributes of the post- redefinition table, and then call this procedure to initiate the redefinition.
