问题如下：
The short-term shutdown point of production for a firm operating under perfect competition will most likely occur when:
选项：
A. price is equal to average total cost.
B. marginal revenue is equal to marginal cost.
C. marginal revenue is less than average variable costs.
解释：
C is correct.
The firm should shut down production when marginal revenue is less than average variable cost.
考点：停止营业点
解析：当边际收益小于平均可变成本时，厂商就应该停止营业。所以应该选C
请问为啥不选A，price等于ATC的时候不就是shutdown point点么NO.PZ2016010802000047问题如下The short-term shutwn point of proction for a firm operating unr perfecompetition will most likely occur when:A.priis equto average totcost.B.marginrevenue is equto margincost.C.marginrevenue is less thaverage variable costs.C is correct.The firm shoulshut wn proction when marginrevenue is less thaverage variable cost.考点停止营业点解析当边际收益小于平均可变成本时，厂商就应该停止营业。所以应该选C老师讲义上不是写着AVC＝AR时就关门吗，为什么这里B不对？

NO.PZ2016010802000047 老师您好，能不能用公式的方法推一下这个C的呢~？我只能从意思方面做出来。
请问A为什么不对 是应该等于AVC吗
