问题如下图：
选项：
A. 
B. 
C. 
解释：
答案C感觉不对，题目是说套利是为了防止下面哪一项，选项C的意思是套利是为了防止相同的标的物卖不同的价格。应该无套利才是这个意思吧
NO.PZ2016031202000007 问题如下 Whiof the following is not a result of arbitrage? A.Convergenof prices. B.Market efficiency. C.The lof similprices. C is correct. Arbitrage forces the prices to converge, thus market efficienimproves. The lof one priis the result of arbitrage, not the lof similprices.中文解析套利迫使价格趋同，从而提高了市场效率。A和B的表述是对的。lof one prices是套利的结果，而不是lof similprices。C表述错误题干要去选错误的表述，选 A说的价格趋同， C说的定义是未来现金流相同两个asset有同样价格所以叫One prilaw这两个看上去说的是同一个事情吧？
