Which statement about Oracle patches is false?

Interim patches, also known as "one-off" patches, are created to provide a specific fix between the releases of patch sets.

Security Patch Update (SPU) is the primary means of releasing security fixes for Oracle products. SPUs are cumulative with respect to prior SPUs and generally contain only security fixes.

Patch Set Update (PSU) is a collection of proactive, stabilizing, cumulative patches for a particular product version (base release or patch set). PSUs are cumulative and include all the security fixes from CPU patches, plus additional fixes.

Patch Set is the main way in which Oracle provides bug fixes in between releases. Oracle bundles a number of fixes, tests them thoroughly together, and packages, then together for easy download and installation.

Terminal Patch Set is an unsupported patch set by Oracle Lifetime Support policies.
