Identify the two options that can be used to patch WebLogic Server without Incurring application
downtime.
A.
automated process using the Admin Server
B.
automated using JDeveloper
C.
manual process with or without Smart Update
D.

E.
automated process using Enterprise Manager 12c
Explanation:
Note:
* Rolling Upgrade is the process of upgrading a running WebLogic Server cluster with a patch,
maintenance pack, or minor release without shutting down the entire cluster or domain. During the
rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while
the other servers in the cluster continue to host your application.

Not D, could not find any resource where someone used WLST for it. Also I believe that patching WLST is not working if you use WLST for it (patching itself?!)
E is more likely because I think they refer to Enterprise Manager Cloud Control 12c and this product indeed has some Automatic Update feature for Weblogic.
“Oracle WebLogic Server patching is now also possible from Oracle Enterprise Manager Cloud Control 12c. This requires a different license: the Oracle WebLogic Server Management Pack Enterprise Edition (EE). The WebLogic Administrator needs to search MOS for patches to apply to a WebLogic Domain, depending on the WLS version and the Platform. The Patching Wizard in Enterprise Manager checks for conflicts, and allows you to apply the patches in parallel or in a rolling manner across the Domain. This can greatly automate the patching of WebLogic Domains. However, WLS Patch Recommendations are not possible at the time of this writing. You need to search for the WLS patches yourself.”

I also feel D can’t be correct answer at all, its E only WLST can’t be used to do patching.
On the other hand 12c EM does has automated workflow which can patch a Weblogic binary and Domain in rolling start fashion, please refer below links.
