Explanation

When upgrading an application in an Oracle Multitenant Application Container, A is correct because Oracle automatically creates an Application Root Clone at the start of the upgrade, allowing application PDBs to remain accessible during the process. E is correct because the ALTER PLUGGABLE DATABASE APPLICATION command requires explicitly specifying both the application name and version numbers (BEGIN UPGRADE 'old_version' TO 'new_version'). F is correct because once the upgrade completes in the Application Root, the application PDBs are automatically synchronized with the upgraded application definition when they are next opened or synced.

B and D are wrong for the same reason: the upgrade must be performed while connected to the Application Root (e.g., APP_ROOT), not CDB$ROOT (D is wrong) and not PDB$SEED (B is wrong) - those are CDB-level constructs, not application-level. C is the mirror distractor to F: it implies PDBs stay in their current synchronized state (i.e., no change occurs), which is false - they do receive the upgrade changes via synchronization.

Memory tip: Think "A-E-F = Always Expect a Fresh start" - A clone is created, Explicit name+version is required, and Finally the PDBs sync up. If you're tempted by B or D, remember: you work inside the Application Root, never at the CDB level, for application operations.
