Answer:
Letter D is correct. Any advantage that one firm has will be short-lived.
Step-by-step explanation:
In this question, there are three retail consumer products companies that use the same resources and capabilities in the production and distribution of their products. Therefore, the most appropriate alternative that describes the market conditions of the scenario described in the question is the letter D, Any advantage of a company will be short-lived.
This is because if the three companies use the same resources and production and distribution capacities, as soon as any company has some kind of advantage, it would be strategically copied and reproduced by the other two companies, and therefore the advantage of one would be canceled.
