The correct option is A Yagna
Offerings like milk, ghee, and cereals are put into the fire during the ceremony of Yagna. Yajna literally means "sacrifice, devotion, worship, offering", and refers in Hinduism to any ritual done in front of a sacred fire, often with mantras. Yajna has been a Vedic tradition, described in a layer of Vedic literature called Brahmanas, as well as Yajurveda.
