What accessibility requirement is stated for CAPTCHA images?

CAPTCHAs must have BOTH audio and hearing formats available. CAPTCHAs must be color-coded for color blindness. CAPTCHAs must be text-based only. CAPTCHAs must be ignored by assistive technologies.

Correct Answer:

CAPTCHAs must have BOTH audio and hearing formats available.

Explanation:

The key idea is to ensure CAPTCHA challenges are accessible by offering an alternative way to verify—an audio option alongside the visual image. Providing an audio format helps users who cannot rely on the visual CAPTCHA, such as those who are blind or have low vision, so they can still complete the task. This aligns with inclusive design by using multiple modalities to convey the same information. The other options fall short because color-coding alone does not guarantee accessibility for all users, an image-only or text-only approach excludes various disabilities, and suggesting that assistive technologies should ignore CAPTCHA defeats the purpose of making the site usable for everyone.
