The correct answer is: b) Nepali community.
Dashain (also called Durga Puja), a major Hindu festival, is celebrated primarily by the Nepali community. It is a ten-day festival that marks the victory of good over evil. The festival is celebrated with great pomp and show, with people exchanging gifts, visiting temples, and feasting.
The Lepcha community is an indigenous community of the Himalayas. They are concentrated in the Indian states of Sikkim and West Bengal, as well as in the eastern part of Nepal. The Bhutia community is another indigenous community of the Himalayas. They are concentrated in the Indian state of Sikkim, as well as in the eastern part of Nepal. The migrant worker community is a diverse group of people who have migrated to different parts of the world in search of work. They come from all walks of life and practice different religions.
Dashain is not a major festival for the Lepcha, Bhutia, or migrant worker communities.
