Answer:
The correct answer is the option C: The amount of labor demanded depends on the demand for the firm's product.
Explanation:
To begin with, in the microeconomics theory we can find the answer to the question base upon the fact that the "derived demand" of labor is known like that because it will always depend on the amount of output that the company sells. Therefore that the amount of labor hired is derived from the amount of product sold. Understanding that if the company sells more of its product then it will hire more workers in order to increase the offer, according to basic supply laws. And that is why that obviously the demand ends up being dependent from the demand of the product itself.
