jQuery event when select option

What's the event to bind for when a select form is selected?

I have something like this:

<select id='list'>
<option value='1'>Option A</option>
<option value='2'>Option B</option>
<option value='3'>Option C</option>
</select>

When Option B is selected, I want some function to run.

So what do I bind, 

$("#list").bind("?", function (){
// How do I check if it's option b that's selected here
//blah blah
});

Although few years late, this actually works also if one select already selected option.

jQuery('#list').on('click', 'option', function () {
    if (jQuery(this).val() === '2') {
        // Do something for option "b"
    }
});

Maybe select() is a more accurated solution:

$('#list').select(function() {
    if ($(this).val() === '2') {
        // Do something for option "b"
    }
});

This jQuery snippet will get you started:

$('#list').change(function() {
    if ($(this).val() === '2') {
        // Do something for option "b"
    }
});
