Which firewall technology can be implemented in all (application, session, transport, network, and presentation) layers...

A circuit-level gateway is a type of firewall technology that can be implemented across all layers of the OSI model, including the application, session, transport, network, and presentation layers. This type of firewall monitors TCP handshaking and session fulfillment between packets to ensure that the session is legitimate. Circuit-level gateways are effective because they do not inspect the packet itself, but rather the transmission attributes to ensure a trusted session is established.
