Answer:
ALL OF THESE
Explanation:
Stupa is a mound-like or hemispheric structure containing relics, i.e. the Ashoka Pillars were spread throughout the Ancient Indian realm, usually next to Buddhist stupas. In this way, the stupa is charged and starts to work, according to their belief. Also, rock chambers with pillars were installed around the stub and the exterior rectangular hall for the community of worshippers as a circumambulatory (pradakshina) path.
