Bamboo clappers are often used as percussion instruments in the:

Sua dance
Gaur dance
Pandwani
Karma dance

The correct answer is: Sua dance.

Bamboo clappers are often used as percussion instruments in the Sua dance, a traditional dance of the Karen people of Myanmar. The dance is performed by a group of women who hold the clappers in their hands and strike them together in a rhythmic pattern. The clappers are made from two pieces of bamboo that are held together by a string. The string is then twisted to tighten the clappers, and the clappers are struck together to produce a sharp, percussive sound.

The Sua dance is a popular dance that is performed at weddings, festivals, and other special occasions. The dance is said to represent the beauty and grace of the Karen women.

The other options are incorrect because they are not traditional dances of the Karen people. The Gaur dance is a traditional dance of the Garo people of India. The Pandwani dance is a traditional dance of the Bhil people of India. The Karma dance is a traditional dance of the Munda people of India.
