Correct answer: C
Fragmentation — Network layer
Fragmentation is handled by the Internet Protocol (IP) at the network layer. When an IP packet is larger than the Maximum Transmission Unit (MTU) of the outgoing link, IP divides the packet into smaller fragments so each fragment fits within the MTU.
Performed by the network layer (IP); fragmentation may occur at the sender or at intermediate routers depending on network behavior and protocol settings.
Reassembly of fragments is done at the destination host.
This is distinct from the transport layer: transport-layer functions (like TCP/UDP) use port numbers to identify application endpoints and do not perform fragmentation.
Other network-layer protocols such as ICMP are also part of the network layer (used for diagnostics and error reporting), not the transport layer.
