The correct answer is: a) Bamboo stilt dances
The Wangala Festival is a harvest festival of the Garo tribe, held in the months of November and December. It is a time for thanksgiving and celebration, and is marked by a number of rituals and activities, including bamboo stilt dances.
Bamboo stilt dances are a traditional form of dance performed by the Garo people. The dancers wear elaborate costumes and masks, and perform intricate steps on stilts made of bamboo. The dances are often accompanied by music and singing, and are a popular way for the Garo people to express their culture and heritage.
The other options are incorrect because:
- Mask dances are not a traditional form of dance performed by the Garo people.
- The 100 Drums Dance is a dance performed by the Khasi people, not the Garo people.
- Traditional fire rituals are not a part of the Wangala Festival.
