Proficiency in which of the following ancient Chinese art forms factored into imperial examinations? A. calligraphy
B. porcelain production
C. working with jade
D. silk production

I think it's A

Explanation:

I think its 'A' because the Chinese did factor into the art forms with this "Besides literary performances, calligraphy skill was of vital importance to the candidates - a faulty brushstroke would reduce a candidate's placement and a poor handwriting would cause its writer being eliminated. " "poetry, and the application of Confucian learning to matters of public policy and statecraft; in later centuries, the prominence of poetry in the exams declined significantly.

I think it’s b because jade was a valuable jewel in the Chinese culture and still is today
