The correct option is A Rich landowners
The process of enclosure was sometimes accompanied by force, resistance, and bloodshed, and remains among the most controversial areas of agricultural and economic history in England. Marxist historians argue that rich landowners used their control of state processes to appropriate public land for their private benefit. Enclosures were now seen as important for making long-term investments on land and for planning crop rotations to improve the soil. Enclosures also helped rich landowners to expand the land under their control and produce more for the market. Hence, Option A is correct.
