Selected Answer: A
A. It relies upon other layers for packet delivery. The application layer is the topmost layer in the OSI model, and it provides services and protocols that directly interact with end-user applications. However, it relies on the transport layer (and lower layers) to ensure packet delivery, as it doesn't handle the actual transmission of data.
