Read the following passage (Passage-2 continued) and answer the question:
The pulse variety Arhar, unlike paddy cultivation, is green and does not need to be burned — it can be ploughed back into the soil. Arhar, unlike paddy, fixes its own nitrogen, which can be ploughed back into the soil. In the case of Arhar, therefore, even after combine harvesting, the leftover biomass, which can't easily be salvaged, can be ploughed back into the soil — which is the concept of simply leaving it. Farmers' income would be maximised by growing it. So if the problem of stubble burning is to be solved, Arhar is the answer.
Which one of the following is the most logical and rational inference that can be made from the above passage?
