Answer:
Isn't she?
Explanation:
The other person is right and I'll explain why!
Both, <u>didn't she?</u> and <u>doesn't she? </u>are <em>improper </em>in this sentence.
Now we would have to choose from <u>isn't she</u> and <u>wasn't she, </u>for this one we will have to go back and look at the sentence.
Jane is British,
We can tell from the keyword<em> "is" </em>that this is present tense.
<u>Wasn't she</u>, being past tense can now be eliminated as an answer choice.
Leaving us with <u>Isn't she</u>, which you can probably already tell is present tense, meaning <u>isn't she </u>is the correct answer.
