The most effective quotation for the curator to include in support of the claim that Dai Ailian's pieces reflect a desire to represent the dances of local communities is:
**(Choice C)** “Yao Drum was inspired by a ceremonial dance Dai witnessed during her time performing field research among the Yao people in the province of Guizhou in 1941 or 1942.”
This quotation directly ties the creation of "Yao Drum" to the local dance traditions of the Yao community, providing clear evidence of Dai's intention to represent and draw inspiration from the dances of the local communities she encountered in China.
