The correct answer is A. Farm mechanization resulted in an increase in farm production.
The mechanization of agriculture describes the development process mainly of cereal cropping and livestock farming, during which production and economic methods radically changed between the end of the 19th and the second half of the 20th century. This development has had a tremendous impact on the labor market and on the population development of rural and urban areas, as the number of inhabitants in the rural villages has steadily increased, while at the same time it has been rapidly increasing in the cities. As a result of mechanization, the total number of human and animal workers in agriculture has fallen dramatically, because even draft animals have hardly been used since the mid-20th century. It also increased the production in the farms, since the use of machinery instead of human work allowed the production of more goods per working days.
