try with .off():

$('#B1').off("click");

FYI:

Only form input elems are having property to get disabled, whether that is type text, select checkbox buttons etc.

While there is no disabled state for a li element, you can simulate the desired behavior like this:

$('#B1').css("color","gray").css("text-decoration","none");

Which will make it appear as if disabled (it will not be underlined and will appear grayed-out).

If in addition you need to disable the event listeners attached to it, you will have to use off():

$('#B1').off("click");

Furthermore, if the element is a link, you will have to prevent it from being clickable, in the following way:

$('#B1').click(function() {
    $(this).preventDefault();  // prevent the default action
    $(this).stopPropagation(); // prevent event from bubbling up
    return false;              // just to be sure
}
