Answer:
B. The Law of Supply and Demand.
Step-by-step explanation:
Labor, like other commodities, is traded in a market. This means that it is subject to the laws of supply and demand. Supply and demand are two concepts in economics that explain the relationship between the quantity of a commodity that producers want to sell and the quantity of it that consumers want to buy. Therefore, if many people require a type of labor, those with that skill will profit. On the other hand, if demand is low for the type of labor workers offer, they might struggle finding anyone who would hire them.
