问题如下图：
选项：
A. 
B. 
C. 
请问BSM中假设不应该是price符合lognormal 而return 符合normal的吗？
NO.PZ201702190300000401 Pri是 constant 还是 continuous 这两是一个意思吗
NO.PZ201702190300000401 continuous prices but not the return stribution. the storeturn stribution but not the volatility. B is correct. Although the BSM mol assumes continuous stoprices, it also assumes thstoreturns are lognormally stribute(not normally stribute.a哪里错了，利率恒定，价格不连续啊
continuous prices but not the return stribution. the storeturn stribution but not the volatility. B is correct. Although the BSM mol assumes continuous stoprices, it also assumes thstoreturns are lognormally stribute(not normally stribute. 看了之前同学的提问，我这边的疑问也是一样的，老师上课说prireturn 是lognorm分布，连续return是normal分布。请下，谢谢。

老师，连续的return不就是服从normstribution的么？我凌乱了……
