B Correct answer
Explanation

The Application Layer (Layer 7) is the top OSI layer that directly interfaces with user applications outside the OSI model. It provides network services like file transfer, email, and web browsing to applications. Lower layers (Physical, Network) handle technical transmission aspects, while Presentation handles data formatting. The Application Layer is the only layer that applications directly interact with.
