I’m leaning towards option A, but I’m a bit confused about where the session layer fits in compared to the transport layer.

I feel like the data link layer and physical layer are definitely at the bottom, but I can't recall the exact order of the others.

I think the order starts with the Application layer at the top, but I'm not sure about the layers below it.
