Answer: C

Explanation:

● Application (Layer 7 or L7): This layer identifies and establishes availability of communication partners, determines resource availability, and synchronizes communication.

● Presentation (Layer 6 or L6): This layer provides coding and conversion functions (such as data representation, character conversion, data compression, and data encryption) to ensure that data sent from the Application layer of one system is compatible with the Application layer of the receiving system.

● Session (Layer 5 or L5): This layer manages communication sessions (service requests and service responses) between networked systems, including connection establishment, data transfer, and connection release.

● Transport (Layer 4 or L4): This layer provides transparent, reliable data transport and

end-to-end transmission control.
