Option 1 should be the correct one. They are the highest layers in the OSI stack. See Wikipedia for more information on OSI model:

The host layers are generally considered to be the transport layer and above. The layers below the transport layer are considered to be the media layers ie. concerned with encapsulating the data with the correct headers and placing the resulting frame onto the physical media.

I'm not sure why you think the correct answer is 4 ?  I would agree with what Daniel has said.
