Which factor is crucial when evaluating image search results for accessibility?

• A. Presence and accuracy of alt text that describes the image.
• B. Image resolution.
• C. File size.
• D. Color scheme.

Answer: (A)

Descriptive alt text is essential because it provides a textual description of an image that screen readers can vocalize for users who cannot see the image. In image search results, this alt text is what accessibility tools reveal about the image’s content and purpose, helping users determine relevance and context. If alt text is missing or inaccurate, the image’s meaning can be lost to those relying on assistive technologies, making the result much less useful. While factors like resolution, file size, and color choices affect how an image appears or loads for sighted users, they don’t convey the actual content or function of the image to someone using a screen reader.
