Which Settings tab should be used to configure the landing page for an ArcGIS Online organization's website?

The landing page for an ArcGIS Online organization's website is configured using the Home Page Settings tab. This section allows administrators to customize the appearance and functionality of the organization's main public-facing page, which can include adding a logo, changing the title, modifying the layout, and choosing what content to display. The Home Page serves as the first impression for users visiting the organization's site, making it crucial to set it up in a way that is welcoming and informative.

The other settings available in the platform, such as Collaborations, General, and Gallery, relate to different aspects of the organization's management or functionality, but they do not specifically pertain to the design and presentation of the landing page. Collaborations focuses on the sharing and working relationships with other organizations, General includes overall organizational settings, and Gallery pertains to displaying various items and resources. Thus, none of these options allow for the direct customization of the landing page like the Home Page setting does.
