For ensuring multimedia content accessibility, you should provide ______ as a fallback option inside the audio or video tags.

Providing transcripts for audio and video content is crucial for accessibility. Transcripts offer a text representation of the content which can be beneficial for individuals who are deaf or hard of hearing, and for those who might not be able to access the content due to technical constraints. Captions serve a similar purpose but are synchronized with the media, while annotations often offer additional, non-essential information.
