This refers to a single actor's own lines and cues.

• A. Script
• B. Prologue
• C. Epilogue
• D. Sides

Answer: (D)

In theatre, the material focused on an individual actor’s performance is known as sides. Sides are sections of the script that include just that actor’s lines and the cues that tell them when to speak or move, and they’re commonly used for auditions and rehearsals to practice a specific moment from the play. They let an actor work with real dialogue and timing without needing the entire script.

A full script contains the entire play for all characters, while a prologue and an epilogue are opening and closing sections of the work, not material specific to one actor’s lines and cues. That’s why sides are the best fit for describing “a single actor’s own lines and cues.”
