Where does parenthetical material start on a transcript page?

In a transcript, parenthetical material is standardized to begin 15 spaces from the left margin. This specific placement is vital for maintaining clarity and organization within the transcript, ensuring that parenthetical comments or clarifications are easily distinguishable from the dialogue or main text.

This layout convention helps readers quickly identify supplementary information without it interfering with the flow of spoken content. By positioning parentheticals consistently, court reporters foster a professional appearance in the transcript that is accessible for judges, attorneys, and other involved parties who may review the document.

The other options do not align with the established formatting guidelines for transcripts, which is why they would not be correct in this context.
