Please remind me about it I forget.
A. in case of
B. in case
C. in no case
D. in this case

A. in case of (答案→)B. in caseC. in no case D. in this case解析：in case万一。是连词，引导条件状语从句。也就是说in case后面是一个完整的句子.in case of的of是介词，介词后面只能带名词性质的词，比如名词、代词等。意思和in case差不多，万一的意思 . in the case of，就...来说, 关于。意思跟上面两个不一样了。一般表示转而提及另一件事情。 所以选B,万一我忘了,请提醒我它的事.
