An administrator at DreamHouse Realty needs to create customized pages for the Salesforce mobile app.

The Lightning App Builder is the primary tool for creating custom user interfaces in both the desktop and mobile versions of Salesforce. For mobile customization, administrators primarily focus on two page types:

App Page: These are custom " landing pages " or " home pages " for an app. They can contain a mix of components like lists, charts, and flows, and they appear as items in the mobile navigation menu.

Record Page: These allow administrators to customize the layout of a specific object (like an Account or a custom Property record) for mobile users. Admins can use " Component Visibility Rules " to show or hide specific sections when the record is viewed on a mobile device, ensuring a streamlined experience on smaller screens.

There is no such thing as a " User Page " (Option B) in the App Builder. While dashboards can be viewed on mobile, they are created in the Dashboard Builder, not the Lightning App Builder (Option D).
