Answer: C. the marginal revenue of building the distribution center is larger than the marginal cost of building it
Step-by-step explanation:
A firm maximises Profit at a level where Marginal Revenue equals Marginal Cost.
If a situation arises where Marginal Revenue is greater than Marginal cost, Profit is not yet maximised and the firm is NOT producing enough goods and services and should increase their output until Marginal Revenue equals Marginal Cost.
If Option C holds true, the Firm SHOULD build another distribution center so as to produce until Marginal Revenue equals Marginal Cost and profit is maximised.
