Part number for AC belt tension pulley

Which one of these is the tension pulley on for the AC belt? I see two pulleys -- one idler and one tension pulley for the main serpentine belt -- but I can't see which one for used for the AC belt?
Edit: I think it's #13. I am not sure why it costs so much though.
