I thought it was A at first, but D makes more sense.

I feel like I’ve seen a similar question in our study materials, and I’m leaning towards option D as well. It just makes sense to me.

I’m a bit confused because I thought the session layer came before the presentation layer, but I can’t recall exactly.

I remember practicing a question like this, and I think option D looks familiar. It seems to follow the standard OSI model.

I think the correct order starts with the physical layer and ends with the application layer, but I’m not sure about the middle layers.
