Q. A semi-circular structure with a dome shape roof erected over the sacred relics of Buddha is known as which of the followings?
Answer: Stupas
Notes: A stupa is a mound-like or semi-hemispherical structure containing Buddhist relics, typically the ashes of Buddhist monks, used by Buddhists as a place of meditation. As most characteristically seen at Sanchi in the Great Stupa (2nd–1st century B.C.), the monument consists of a circular base supporting a massive solid dome from which projects an umbrella.
