Poems with fu.

Fu originated in the Warring States Period, flourished in the Han and Tang Dynasties, and declined in the Song, Yuan, Ming and Qing Dynasties. Qu Yuan's works are called Fu in historical records, and Qu Yuan's works are also called Fu in Hanshu. Later generations praised history and Han, so they called the works of Qu Yuan and others Fu. In your C option, "I am a descendant of Emperor Levin, but I can test Bo Yong" comes from Qu Yuan's work Li Sao, which is both a fu and almost its source.
