The correct option is A Langar
Bhela Ghar is the house made of hay which is burnt on the second day of the festival of Bihu celebrated in Assam. Dhoti-Gamosa is the traditional attire worn by men during Bihu. Uruka is the name of the first day of the Bihu festival.
But, Langar is not associated with Bihu. It is a free vegetarian meal offered to the visitors of the Golden Temple in Amritsar, Punjab.
