The Network layer (Layer 3) of the OSI model uses connectionless protocols, most notably IP (Internet Protocol). IP is a best-effort delivery protocol — it doesn’t establish a session or confirm delivery.

Selected Answer: B
The Network layer in the OSI model is responsible for routing packets between devices across different networks. It uses connectionless protocols such as IP (Internet Protocol), which sends data packets independently without establishing a dedicated connection between sender and receiver.
