I've taken a grammar test on an online site, and I've got 3 choices to choose out of them the correct one:
A. At any time, was I informed
B. At no time, was I informed
C. At no time was informed I
I had no clue about the correct answer because all of them looked quite odd to me. Anyway, when I cheked the correct answer is B: "At no time, was I informed". Now, since non of them has a question mark at the end of the sentence, I'm really confused what kind of sentence it is, while the lexical verb (was) precedes the pronoun (I), which is typically happens in interrogative sentences. I'd love to get an explanation for that.
