B. writing the first novel.

Explanation:

Although it is a matter of debate, many agree that the Tale of Genji can be considered the first novel ever written, this mostly because of the psychological nature of the narrative along with the structure of the tale which clearly falls within the scope of what is considered a novel (length, character development and setting, dialogue and polyphony, and detailed societal descriptions). The novel was written by a noblewoman by the name of Murasaki Shikibu in the 11th century of our time.
