Attributes are used to provide additional information about HTML elements.

• A. They provide additional information about elements
• B. They define the element's text content
• C. They mark the opening tag
• D. They control the document language

Answer: (A)

Attributes provide extra information about HTML elements. They live in the opening tag and modify how an element behaves or how it’s presented, without changing the element’s actual content. For example, the href attribute on a link tells the browser where the link goes, the src attribute on an image specifies the image file, and the alt attribute provides a text description for accessibility. Class and id attributes help with styling and scripting, and data- attributes store custom data for scripts to use. This broad role—adding metadata and controlling behavior—is why this statement is the best match. The other ideas don’t fit as well. Text content is determined by what’s between the opening and closing tags, not by attributes. The opening tag is simply where attributes appear, but that doesn’t explain what attributes do overall. Language is set by a specific attribute (lang) on the root element, which is just one example of an attribute’s use and doesn’t describe the general purpose of attributes.
