What is HTML primarily used for?

HTML, or HyperText Markup Language, is primarily used for controlling the format and presentation of data on the web. It provides the basic structure for web pages, allowing developers to define elements like headings, paragraphs, links, images, and more. By using various HTML tags, developers can specify how content should be displayed in the browser, which is essential for creating visually appealing and accessible web experiences.

HTML is not designed for storing data in a database; instead, databases use structured query languages (like SQL) to manage data. While HTML can be involved in processing data, such as through forms, it does not inherently handle data queries itself. Additionally, managing server interactions is typically done with server-side languages and technologies rather than HTML, which functions primarily on the client side.

Thus, option B accurately describes the fundamental role of HTML in web development, focusing on how it formats and presents data rather than handling storage or processing tasks.
