Answer: D) can assume the firm is not using the most efficient technology
Explanation:
The profit maximizing point of production for a company is the point where the marginal cost of production equals the marginal revenue. At this point, resources are being fully utilized efficiently to produce goods and any increase in production quantity would result in a loss.
In this case however, the company is at the profit maximizing quantity and still making a loss (selling price is less than average total cost). This can only mean that the company is not utilizing resources efficiently and this can be due to a lack of efficient technology.
