In china, music was inseparable from select one:
a. poetry
b. speech
c. dance
d. religion

Like everything else in China, the music is inextricably tied to the Chinese philosophy. By its nature, the Chinese music is characterized by gentle sounds reminiscent of a gurgling brook, or birdsong. Many medieval Chinese musicians specially imitated the sounds of nature, thus creating a harmony of music and nature.
D. religion

Ithink that c would make the most amount of sense.
