Which statement describes header, nav, and footer elements?

• A. They are semantic elements
• B. They are style elements
• C. They are form elements
• D. They are basic elements

Answer: (A)

Header, nav, and footer are semantic elements in HTML5. Semantic means they describe their purpose in the document, so both humans and machines can understand the page structure. The header signals introductory content, the nav groups the main navigation links, and the footer contains concluding information for the page or section. This clarity helps screen readers interpret the layout and improves search engine understanding and accessibility. They’re not style elements like the CSS style tag, nor form elements like input or button, and they’re more informative than a generic container such as a div.
