Correct Option: A

The Vedic state derived its revenue from people's contribution, technically known as ‘Bali'. Of all the terms used in connection with the items of revenue to the state, it is 'bali' which is mentioned most in the Vedic texts. Its use is, however, not restricted exclusively to the fiscal sense but also to "offerings to a god" and to tributes paid by hostile tribes to the king. A man is depicted in the Rig Veda as presenting oblation (bali) to Agni.
