In a communication between 2 computers, each layer of the OSI model communicates with: (a) the layer above; (b) the layer below; and/or (c) the same layer on the other computer?

It depends, If your computer is trying to send data to other computer the layer above is the one communicates with the layer below but if your computer is receiving data from other computer the layer below communicates with the layer above.
So, when your computer is trying to communicate with other computer the (7)APPLICATION LAYER send request to (6)PRESENTATION LAYER. The (6)PRESENTATION LAYER will then respond to service request from (7)APPLICATION LAYER and issue service request to the (5)SESSION LAYER. The (5)SESSION LAYER will then respond to service request from (6)PRESENTATION LAYER and issue service request to the (4)TRANSPORT LAYER and so on and so forth.
But when your computer received communication from other computer the (1)PHYSICAL LAYER is the first one to handle the communication and it will then issue service request to the (2) DATA LINK LAYER. The (2)DATA LINK LAYER will then respond to service request from (1)PHYSICAL LAYER and issue service request to the (3)NETWORK LAYER. The (3)NETWORK LAYER then respond to the service request from (2)DATA LINK LAYER and issue service request to (4)TRANSPORT LAYER and so on and so forth...
Hope this Help you.

D) none of the above. They talk by sending a packet made up of the 7 layers. [1][2][3][4][5][6][7]information[7][6][5][4][3][2][1] Look up the term encapsulation. This is a very basic example.
