Option A. received less money for their crops is the correct answer.
The Green revolution's large crops made poor farmers to receive less money for their crops. As the production increased to a large extent due to the Green Revolution, it lead to the fall of prices of crops and thus the poor farmers had to sell their crops at cheap rates.
Economically, green revolution was not very fruitful for the poor farmers. Due to the revolution, the agricultural production increased tremendously.
This lead to more supply with respect to demand in the market due to which the price of agricultural produce reduced. Out of market pressure, the poor farmers were forced to sell crops at a lower price.
