Answer: A) aesthetics.
When discussing the "aesthetics" of a work of art, what you are studying is the art, beauty or taste that an object possesses. A discussion on aesthetics centers on the form of a work more than it does on its contents. It discusses the way in which an author conveys a feeling or a message as well as the way in which readers receive it. Finally, aesthetics also analyze how a particular work of art relates to the principles of the movement it identifies with.
