Which configuration option in the home page editor is used to edit the Contact Us link?

The Footer configuration option in the home page editor allows users to edit the "Contact Us" link because this link is typically incorporated in the footer section of most web pages, including ArcGIS Online home pages. The footer is designed to contain important links and information that users might want to access readily, such as contact details, legal information, or quick navigation links.

By editing the footer, administrators can customize the appearance and functionality of the "Contact Us" link, ensuring that it directs users to a relevant contact page or provides necessary contact information. This customization helps enhance user experience and ensures that users can easily find assistance or reach out for support when needed. The other options, such as Design, Header, and Content Blocks, serve different purposes in page configuration and do not typically include the "Contact Us" link.
