Which of the following reflects diseconomies of scale?
As a firm grows larger in scale by expanding its plant and capacity, its average cost of production rises.
As a firm adds more units of a variable input to a fixed input, the marginal product of the variable input falls in the short run.
Average fixed cost declines in the short-run as more output is produced.
As output is expanded, average total cost falls because marginal cost is less than average total cost.
