Which of the following is an example of metadata about a webpage?

Metadata refers to data that provides information about other data. In the context of a webpage, metadata includes elements that describe the webpage’s content, structure, and behavior. The title of the webpage is a clear example of metadata because it serves as a concise descriptor that tells users (and search engines) what the webpage is about. It is an essential element that appears in the browser tab and search engine results, helping to summarize the page's purpose in a way that is easily accessible.

The main content of the webpage, images, and links, while they are critical components of the webpage itself, do not fall under the definition of metadata. They represent the primary information on the page rather than descriptive attributes that help to characterize or define that information. Therefore, the title specifically fits the definition and role of metadata, making it the correct answer.
