with DEPARTMENTS that exists in another tablespace,MASTERTBS.

Which two actions will permit the TSPITR to work?(Choose two.)

A. Taking the MASTERTBS tablespace offline

B. Dropping the relationship between the tables

C. Adding the MASTERTBS tablespace to the recovery set

D. Putting the MASTERTBS tablespace in read-only mode
