What is the DOM used for?

• A. To style HTML with CSS.
• B. To fetch data from the server.
• C. A standard that enables you to manipulate HTML elements and attributes in a Web document.
• D. To render images in the browser.

Answer: (C)

The DOM is a programming interface that represents a web page as a structured document you can manipulate with code. It exposes the page as a tree of objects—the elements, their attributes, and the text inside them—so scripts can read and change anything on the page dynamically. This is why you can select an element, update its content, add new elements, or alter attributes like class or src without reloading the page. The DOM is a standard defined by the W3C, so JavaScript in any browser can interact with the same document structure in a predictable way.

This is the best choice because it directly describes what the DOM does: it enables you to manipulate HTML elements and their attributes within a Web document. It’s not primarily about styling (that’s CSS), data fetching from servers (that’s fetch and other network APIs), or rendering images (that’s the browser’s rendering engine, not the DOM itself). The DOM provides the programmatic access, while styling, data transfer, and rendering are handled by other parts of the browser.
