Not sure why this isn't working. The question is pretty confusing..

Wondering how to get this to work. The question is pretty confusing.

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h2>Student List</h2>

    <ul class="student-list">
        <li>James McAvoy</li>
        <li>Alena Holligan</li>
        <li>Wade Christensen</li>
        <li>Matt Krzyzynski</li>
    </ul>

    <script

Though this might be a good situation to use it, the instructions did not ask for descendant filtering, so you won't need that 2nd argument ('ul').

And what about 2nd option?

That's the same as Chase's code with the 2nd argument removed, except you also added the tag name to the class selector. That works, and is perhaps more literally correct for the instructions, but it's not needed to pass the challenge.

Hi,

We need to modify code.

$('document').on('click', 'ul.student-list', function(event) { console.log("Option 1") });

or

$('ul.student-list').on('click', function(event) { console.log("Option 2") });

Both option will work

FYI: The first suggestion shown here does not follow the instructions, and will not pass the challenge.
