Your multitenant container database (CDB) contains pluggable databases (PDBs), you are connected to the HR_PDB. You execute the following command:SQL CREATE UNDO TABLESPACE undotb01 DATAFILE ‘u01/oracle/rddb1/undotbs01.dbf’ SIZE 60M AUTOEXTEND ON;What is the result?（）A. It executes successfully and creates an UNDO tablespace in hr_pdb.B. It falls and reports an error because there can be only one undo tablespace in a cdb.C. It fails and reports an error because the CONTAINER=ALL clause is not specified in the command.D. It fails and reports an error because the CONTAINER=CURRENT clause is not specified in the command.E. It executes successfully but neither tablespace nor the data file is created.
