I would say that the best answer is A. C is definitely not the answer because of course, there is a relationship between art and literature.
Studying literature involves reading, thinking, interpreting, discussing, and writing. Studying art is analyzing and critiquing the artwork, as well as learning about the history of art. Putting both literature and art together creates a better understanding of the artwork and a more in-depth discussion about the artwork itself.
(I apologize for the late reply. Hopefully this answer is helpful to you though.)
