Challenge 1 / 1

Remember that tasty assets/img/smores.png file we have? Now we want to refer to it from inside assets/styles/app.css. What's the correct way:

background-image: url('/img/smores.png');

background-image: url('img/smores.png');

background-image: asset('img/smores.png');

background-image: url('../img/smores.png');
