The correct answer is: a) 100 Drums Dance.
The Wangala Festival is a harvest celebration of the Garos, an ethnic group native to the Garo Hills in Meghalaya, India. The festival is held over a period of three days, and is marked by feasting, dancing, and singing. The highlight of the festival is the 100 Drums Dance, in which hundreds of drummers perform a synchronized dance. The dance is said to represent the unity of the Garo people, and is a way of thanking the gods for a bountiful harvest.
The other options are incorrect because:
- Chambil Mesara is a type of Garo folk song.
- Sword Dances are a type of Garo dance that is performed with swords.
- Mask Dances are a type of Garo dance that is performed with masks.
