Correct Answer:
C. It faces diminishing returns and inefficiency
When an industry operates beyond the optimum level of production, it means that resources are being overutilized, leading to diminishing returns and inefficiency. This occurs because, after a certain point, adding more inputs (like labor or capital) to a fixed amount of other inputs will result in smaller increases in output, eventually leading to higher per-unit costs.
- A: It maximizes profits is incorrect because profit maximization occurs at the optimum level, where marginal cost equals marginal revenue, not beyond it.
- B: It achieves economies of scale is false. Economies of scale are typically achieved up to the optimum level; operating beyond it can lead to diseconomies of scale.
- D: It experiences rapid growth is unlikely. Inefficiency and diminishing returns hinder sustainable growth.
