For video-only content, what accessibility option ensures equivalence?

• A. A transcript or captions for the video are required.
• B. An equivalent test or audio alternative is available.
• C. No accessibility accommodations are needed.
• D. Video-only content must include an on-screen signer.

Answer: (B)

Equivalence in accessibility means providing information in a format that communicates the same content to users who can’t access the original modality. For video-only content, the best way to ensure equivalence is to make an equivalent test or an audio alternative available. This gives the same material in another modality, so anyone can access the information even if they can’t view the video. Captions or transcripts help with specific needs, but they don’t guarantee a complete substitute for the visual content when the core information relies on what’s shown. An on-screen signer aids some users, but it isn’t universal access for all scenarios. Providing an equivalent test or audio alternative ensures the same information is accessible through another channel.
