The oj-sp-dashboard-landing-page is a specific Oracle JET component used within Visual Builder to structure dashboard pages. According to the official Oracle JET documentation, which governs Visual Builder components, the page-title attribute is explicitly defined as a required property. This attribute provides the main heading for the page, which is a fundamental element for user interface structure, context, and accessibility. The component's definition mandates its presence for proper rendering and functionality. The other options, such as page-subtitle and in-flow-back, are optional attributes that provide additional descriptive text or control layout behavior but are not essential for the component's instantiation.

B. Page Subtitle: This is an optional string attribute used to display supplementary text under the main title.

C. In Flow Back: This is an optional boolean attribute that controls the layout of the back button; it defaults to false.

D. Primary Action: This refers to an optional named slot, not a required attribute, used for embedding components like buttons.
