The correct answer is Dom.
Domkach is a folk dance performed by the Dom community in Bihar. It is a lively and energetic dance that is often performed at weddings and other celebrations. The dance is performed by a group of men and women who move in a circle, clapping their hands and singing. The dancers often wear colorful costumes and jewelry.
The Dom are a scheduled caste community in India. They are traditionally considered to be a low caste and have faced discrimination and oppression. However, in recent years, the Dom have been working to improve their social and economic status. They have formed organizations to advocate for their rights and have started businesses to generate income.
The Domkach dance is a way for the Dom to express their culture and identity. It is a celebration of their heritage and a way to connect with their community. The dance is also a way for the Dom to challenge the stereotypes that are often associated with them. It is a powerful statement of their pride and resilience.
