  A.It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root only.

  B.It fails and reports an error because the CONTAINER=ALL clause is not used.

  C.It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.

  D.C.It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.D.It fails and reports an error because the CONTAINER=CURRENT clause is not used.
