Final answer:
Without specific information in the text regarding showtimes or tickets, we cannot determine the exact action Renaldo should take to bring his sister to the play, but typically, contacting the theatre directly is a good starting point for obtaining such information.
Step-by-step explanation:
Based on the text provided, there is no direct information about how Renaldo should take his sister to see a play. However, if we consider the typical process that theatres use for organizing auditions and productions, it might be reasonable for Renaldo to seek information about the play by contacting the theatre directly. Even though the specific options (a through d) cannot be confirmed as correct based on the text alone, generally theatres provide information about showtimes and how to watch a play to the public through a contact number or other means of communication.
