When using しか, which part do we have to negate?


I want to say "Mathematics is the only thing I trust." using しか. But I am not
sure which part I have to negate.

Which one is the correct one? A or B?

> A: 数学しか信頼できるものじゃない。
>
> B: 数学しか信頼でないものだ。




Both your sentences are unnatural. 数学しか信頼できない is natural.
