The marginal cost of production shows the change in a​ firm's total cost from producing one more unit of a good or service. what is the shape of the marginal cost​ curve? ​graphically, the marginal cost curve is
a. shaped like a​ hill, initially rising when the marginal product of labor is falling and then eventually falling when the marginal product of labor is rising.
b. a u​ shape, initially falling due to diminishing returns and then eventually rising due to specializationspecialization.
c. a u​ shape, initially falling when the marginal product of labor is rising and then eventually rising when the marginal product of labor is falling.
d. a u​ shape, initially falling when the marginal product of labor is below marginal cost and then eventually rising when the marginal product of labor is above marginal cost.
e. shaped like a​ hill, rising when the average cost of production is rising and then eventually falling when the average cost of production is falling.
