Answer:
A
Step-by-step explanation:
C and D are easily eliminated; farmer life did not grow. It's been steadily shrinking since the 1700s. B sounds good initially, but people were moving to cities, where all the attainable jobs and payable rents were - most people couldn't afford to just buy a ton of land and start farming, and suburbs didn't really exist for the same reason. So it has to be ‘A’.
