Concept:An epilogue is a closing section that appears at the end of a play or literary work.
Explanation:After the main action ends, an epilogue speaks directly to the audience.
Its main role is to conclude the story by summing up what has happened.
It can also explain the outcome of events or comment on the theme.
An epilogue does not introduce a play, nor does it introduce or develop characters.
That work is done by a prologue and the main plot.
Therefore, the correct function of an epilogue matches the description “sums up a play.”
Answer:C. sums up a play
