Answer is indeed “A”at Layer 5, but Layer 5 is NOT Application.
Layer 5 of OSI is Session. Circuit level gateway work at Layer 5 – Session

Answer: A Layer 5-Application
Circuit level gateways are deployed at the *Session layer* of the OSI model and they monitor sessions like TCP three way handshake to see whether a requested connection is legitimate or not.
The TCP/IP model includes the Session layer (and Presentation) in the Application layer.
