The uploaded study guide identifies C. Recognizing peers with badges as the correct answer.
The question is specifically about increasing customer engagement in an Experience Cloud portal that is already performing well. The study guide selects peer recognition through badges because it introduces a direct participation and recognition mechanism within the community experience.
Badges can acknowledge contributions or activity, creating a visible form of recognition between participants. In the context of the answer key, this is considered more directly related to engagement than changes focused mainly on presentation.
Option A, personalized branding, changes how the portal looks or feels for an audience, but branding alone does not provide the same participation-oriented mechanism.
Option B, customizing page layouts, can improve information organization, yet the portal is already described as performing well. Layout changes therefore do not target engagement as directly as recognition does.
The key distinction in the study guide is between experience presentation and community participation. If the objective is specifically to encourage engagement, a mechanism that acknowledges users' contributions provides a stronger engagement-oriented feature than simply changing visual design or layout configuration.
