dont know——a that l have passed the English examb if l had passed_英语解答

dont know——
a that l have passed the English exam
b if l had passed the English exam
c what marks have l got in the English exam
d how well l did in the exam
选b,可是这句话明明是陈述句,为什么还用if
可是怎样看出是陈述句，怎样看出是疑问句改成陈述句

本来问的是have i passed the english exam 我的英语考试过了么?放在l dont know后做宾语,宾语从句要用陈述语序,问句要用if 引导此宾语从句,也就是间接引语,人称时态都做相应的变换,成了 if l had passed the English exam
