The correct answer is C. Speaker . In Relativity transcript review, the Word Index is used to navigate the transcript content by words and speakers appearing in the testimony. The transcript review experience centers on transcript text structure, including speaker-based navigation, rather than fields like associated facts or exhibits, which belong to different transcript-management features. Relativity's transcript tooling distinguishes transcript content navigation from fact management and exhibit linking, so Speaker is the correct Word Index field from the choices given.
The other options correspond to different transcript-related concepts. Associated fact belongs to fact management workflows, Exhibit number relates to transcript exhibits, and Count is not the specific transcript Word Index field tested here. While the current public help snippets I found do not surface the exact Word Index field list in one compact line, the available transcript/user documentation supports the transcript- review distinction that makes Speaker the correct answer. This one is slightly less directly quoted than some of the others, but it remains the best verified answer from Relativity transcript behavior.
