The Gujarati dish which is prepared by keeping the pot upside down -

The best time of the year to eat stews like undhiya is in the winter. Fresh spices and all the vegetables were added to a clay pot. The pot was kept between hot coals with a lid on it.  On the fields, this unique stove slowly cooked the vegetables. The pot was positioned upside down. Because of this, the meal was given the Gujarati name undhiya, which means "upside down."

Therefore, the correct answer is option (4).
