ARIA roles and semantic HTML

If a developer uses a

to create a navigation menu instead of a

tag, which ARIA role should they add to maintain accessibility?

A role="main"

B role="banner"

C role="navigation"

D role="contentinfo"

💡 Hint

ARIA roles describe the purpose of elements to assistive technologies.

When semantic tags are not used, ARIA roles can provide the same meaning. The role="navigation" tells screen readers that the element is a navigation region.
