Explanation:
The name of this collection of images is in fact <em>Marilyn Diptych</em>, so you can be certain that B is the correct answer here. The Greek word diptych refers to something consisting of two parts, and was often used in Christian art and churches to refer to a painting in two parts that can close like a book.
