An epilogue

An epilogue is a concluding section added to a literary work, such as a play, novel, or memoir. Its purpose is to provide closure to the story or to offer final thoughts on the themes and characters. Unlike a prologue, which is an introductory section, an epilogue comes at the end of the work and is often used to sum up the events of the story or to offer a glimpse into the characters' futures. It can also be used to reflect on the themes or messages of the work, or to provide a final commentary on the story. Therefore, option C - "sums up a play" - is the correct answer to this question.
