Answer:
B. it ignores the firm's demand curve.
Step-by-step explanation:
A: With the help of average cost pricing, the fixed cost can quickly estimate. Therefore, it cannot be the answer.
C: The average cost must consider the effect of variable cost. Therefore, it is also the wrong statement.
D: It is easy to estimate profit if there is an average cost pricing.
B: average-cost pricing always ignores the demand curve because it is a "U" shaped curve. Because after a certain level of product selling, the average cost is increasing. On the other hand, demand curve is such that if the price decreases, the quantity demanded increases. Therefore, it is a downward slopping curve. Hence, it is understood that, average-cost pricing ignores demand curve.
