You don't think it is wrong,isn't? You don't think it is wrong,is it? You don't think it is wrong,do you? Which one is correct??????????

The little tag at the end of sentences like this always repeats the subject of the sentence.

> YOU don't think it's wrong, do YOU?
> IT isn't wrong, is IT?

Furthermore, the tag reverses the positive-negative of the main clause.
> This ISN'T wrong, IS it?
> This IS wrong, ISN'T it?

Other examples:
> He was late, wasn't he?
> He wasn't late, was he?

> Judy is getting married, isn't she?
> Judy isn't getting married, is she?

> The weather is awful, isn't it.
> The weather isn't bad, is it.

The expression is written as a question, but very often the vocal inflection of the speaker is to make it a declarative statement, not a question. That is often symbolized by omitting a final question mark.

Answer:
You don't think it's wrong, do you?

The last one, 'do you' is is the only correct version.

you don't think it's wrong do you?

"Do you" is correct because "you" are the one who is thinking. If the subject were "it," then "isn't" would be correct, but, because it isn't the subject, it isn't correct.

It's wrong

None of the above.
"Do you think it wrong?
"Is it wrong?"
