The correct solution is C. Enablement Site to build and assign custom modules, exactly as specified in the uploaded study guide. An Enablement Site is appropriate because the requirement is broader than simply showing users contextual assistance. Cloud Kicks requires structured, custom product training that can be delivered as learning content to internal users and leadership. Salesforce's Enablement functionality supports publishing modules and assigning relevant learning content to users. Salesforce documentation specifically explains that administrators can assign modules published on an enablement site and that users can complete assigned content from within Salesforce. Option A addresses a narrower use case. In-App Guidance prompts are effective for contextual onboarding, feature announcements, and short instructional interventions within the user's workflow, but they are not a replacement for a structured custom learning curriculum.

Option B provides an environment where users can experiment, but a sandbox does not inherently provide organized learning modules, assignments, learning progression, or formal enablement content.

The UX requirement here is therefore solved by selecting the platform capability that supports repeatable, organized, assignable learning experiences, rather than merely contextual assistance or an experimentation environment.
