E is not correct.
Pluggable databases are not only used for database consolidation. There are lot of benefits of pluggable databases.

C and D are correct answer. But In my opinion E is a correct answer too.
In my opinion D is not correct, we can patch a single PDB.
See:
http://www.oracle.com/technetwork/database/multitenant/overview/index.html
“To patch a single pluggable database, you simply unplug/plug to a multitenant container database at a different Oracle Database software version.”
I agree, but the question is about 1 CDB with 3 PDB.
So I think C and D are correct.
A new option for Oracle Database 12c, Oracle Multitenant helps customers reduce IT costs by simplifying consolidation, provisioning, upgrades, and more.
