Answer:
A. The author wants to keep the reader or listener engaged.
Explanation:
When there is not a resolution on a novel, a play or a tale, it´s called a cliff hanger if it is going to continue, or an open ending if that´s the actual ending of the story, writters often do this to create suspense and keep the listeners of readers engaged witht the story and with a strong desire to keep reading the next story or the next book.
