When the following sentence is pronounced emphasizing "Everybody", which is the speaker's intent? (←I'm a Japanese and this is the sentence I made changing Japanese into English, so it might be grammatically incorrect...)

Everybody knows she likes jazz.

1.It's not he who likes jazz.

2.Who told you that she dislikes jazz?

3.Not classical music but jazz is her favorite kind of music.

4.You are the only one that doesn't know she likes jazz.

I think 2 or 4 is collect.

I would be grateful for your help.
