What attribute is used in an anchor tag to specify the link destination?

The attribute used in an anchor tag to specify the link destination is "href." This stands for "hypertext reference," and it defines the URL or the address to which the link points. When a user clicks on the anchor tag, the browser navigates to the URL specified in the href attribute. This is fundamental to creating hyperlinks in HTML, allowing for navigation between different pages or resources on the web.

The other options do not serve this purpose. For instance, "src" is commonly associated with elements like images or scripts to specify their source location, while "link" and "path" are not standard attributes used in anchor tags. Thus, href is essential for enabling hyperlinks in web development.
