What is an anchor tag used for in HTML?

The anchor tag in HTML is specifically utilized to create hyperlinks that connect one webpage to another or link to various resources, such as a file or an email. This functionality is essential for web navigation, allowing users to click on the link and be directed to the specified destination. The tag itself is written as <a> followed by attributes like href, which specifies the URL of the page or resource being linked to, enabling the establishment of these connections between different locations on the web.

The other options refer to different purposes in HTML. For instance, styling text is typically managed through CSS (Cascading Style Sheets), rather than an HTML tag. Embedding images is accomplished using the <img> tag, which directly incorporates visual content into a webpage. Creating forms is done with the <form> tag, which organizes and manages user input fields for data collection. Each of these functionalities utilizes distinct tags and attributes specific to their roles within HTML.
