Which of the following might be a component of "Main Content" on a webpage?

The concept of "Main Content" on a webpage refers to the primary material that provides valuable information and engages the user. This includes any significant text, images, and multimedia that contribute directly to the purpose of the page. Videos and images are key components of the main content because they help illustrate ideas, tell stories, or present information in an engaging and visually appealing way. When users are looking for substantial content on a webpage, they often seek out these elements, which enhance understanding and increase user engagement.

Other options like banner ads, links to other sites, and navigation menus serve different purposes. Banner ads are primarily for advertising and monetization, links to other sites facilitate navigation but do not constitute the core content of the page, and navigation menus are meant to help users find their way around the site rather than deliver the main message or purpose of the specific page. Thus, while these elements are important for user experience, they do not belong to the category of main content as they don't provide the primary value that users are typically seeking on the page.
