I believe the answer is B
Conditions before the Industrial Revolution were terrible. Child mortality was high and the children who survived, barely had enough to eat. You see, because of The Little Ice Age, agriculture was terrible. And before the revolution, most of Europe was agriculture based. The lack of food made people stunted and killed many. The food that could be harvested, were taxed and there was almost no profit.
Well there could be problems with food, and if there is a sickness, or a desater, like flooding around you could not move on. Also the population can reduce food, and water.
