Which attribute provides text alternatives for images for accessibility?

• A. alt
• B. src
• C. title
• D. href

Answer: (A)

Providing text alternatives for images is essential for accessibility because users who rely on screen readers or who have images disabled need to understand what the image conveys. The attribute that supplies that description on an image element is the alt attribute. Alt text describes the image’s content or function, and screen readers read this text aloud so the user understands what the image represents. If the image can’t load, the alt text serves the same purpose by conveying meaning. For decorative images that don’t add information, using an empty alt helps keep assistive technology output uncluttered. The other attributes don’t serve this purpose: src specifies the image file to display, not a description; title can show a tooltip but is not reliably announced by assistive tech; href is used to define a link destination on anchors, not to describe images.
