Hub: Layer1 since it act as a media repeater
Switch: Layer2 it switch packets based on MAC Address
Router: Layer3 it Route Packets based on IP Address
If you mean Where each device work here the answer:
Hub >>> Layer1 or Physical Layer
Switch >>> Layer2 or Data Link Layer
Router >>> Layer3 or Network Layer this is typically but you can add module to make router work as switch also
tip: router is very flixable devicd.
Well, I think your question is a bit unclear. What I got is that your question is about the IOS layer in which hub, swirch and router operate. If that's the question, then the answer is layer one (physical layer).
