问题如下：
A firm in perfect competitive market will enlarge its output when:
选项：
A.marginal revenue > 0.
B.marginal revenue > market price.
C.market price > marginal cost.
解释：
C is correct. When price > marginal cost, a firm in perfect competition can enlarge its output. In equilibrium, profit is maximized when P=MC.
考点：完全竞争厂商
解析：完全竞争厂家利润最大化的条件是P=MC，如果当P>MC，那么厂家就可以通过扩大生产的方式进一步提升利润。
从公式上理解，MR=△TR➗△Q＞0，说明Q和TR是正相关，那么如果提升Q，TR也会增加。不也是会扩大生产么?
