The correct answer is: a) Kud
Kud is a traditional dance of the Uyghur people of Xinjiang, China. It is a circle dance that is often performed at weddings and other celebrations. The dance is accompanied by singing and the playing of traditional instruments, such as the dutar and the dap.
The singing of traditional folk songs called ‘Bakhan’ accompanies the Kud dance. Bakhan are songs that are often about love, loss, and the beauty of nature. The songs are sung in a high-pitched voice and are accompanied by a simple melody.
The other options are incorrect because they are not dances that are accompanied by the singing of Bakhan songs. Rouf is a dance of the Tajik people of Tajikistan. Wuegi-Nachun is a dance of the Kyrgyz people of Kyrgyzstan. Hikat is a dance of the Kazakh people of Kazakhstan.
I hope this helps!
