Probably not the answer you're looking for, but it's the correct one.

All of them. The OSI model is just that-- a model representing Network communication. The OSI Layer's are defined to detail specific functions that are preformed in network communications in a manner that is easier to comprehend.

Some protocols, by their nature, lend themselves to predominantly work in one layer over others but they all pass through all 7 conceptual layers.

================
Take a look at these OSI examples:

DHCP goes all the way to layer 7.
