hello Dr Zack,i'm kissob ,an esl teacher in china.one of my co-workers asked me how to use ,wasn't there? and didn't there? or if both are all correct.i was confuse,for in the sentence he used it seems both could go.

here's the sentence

it seems to be rainy yesterday,
(a)wasn't it? (b)was there?(d)didn't there?

happy if i could read from you.
