is there any methode for disable like adding some css property ...actually i don't know..

To unbind a live handler, call die. (I didn't make that up)

However, if bestAnswer is a single element, there's no point in using live instead of bind.
live is designed to be used with a selector that will match elements in the future.

Also, if you can write bestAnswer.live, you don't need to write $(bestAnswer), since it's already a jQuery object.
(As opposed to a DOM element, selector, or HTML string which you would need to call $ on)

You could just do it in your handler, no unbinding necessary:

$("selector for answers here").live('click', function()
{
    if (!$(this).hasClass("IsBestanswer")) {
        // do something, this isn't the best answer
    }
});
