问题如下：
Normal profit is best described as:
选项：
A.zero economic profit.
B.total revenue minus all explicit costs.
C.the sum of accounting profit plus economic profit.
解释：
A is correct.
Normal profit is the level of accounting profit such that implicit opportunity costs are just covered; thus, it is equal to a level of accounting profit such that economic profit is zero.
考点：Normal profit
解析：正常利润就是经济利润为0时候的利润。
正常利润应该等于收入减去显性成本的同时还要减去隐性成本。B选项不入选
C选项就是个打酱油的选项，不必管它。
中文解析“正常利润应该等于收入减去显性成本的同时还要减去隐性成本”。要减去隐形成本？没明白
