What is the TCP/IP 'Internet layer' equivalent in the OSI model, and which three protocols operate primarily at this layer?

• A.The TCP/IP Internet layer maps to OSI Layer 4 (Transport); protocols: TCP, UDP, TLS
• B.The TCP/IP Internet layer corresponds to OSI Layer 3 (Network layer); protocols operating at this layer include: IP (IPv4 and IPv6) for logical addressing and routing, ICMP (Internet Control Message Protocol) for error reporting and diagnostics, and ARP (Address Resolution Protocol) for mapping Layer 3 IP addresses to Layer 2 MAC addresses (technically L2.5 but associated with the Internet layer in TCP/IP)
• C.The TCP/IP Internet layer maps to OSI Layer 2 (Data Link); protocols: Ethernet, Wi-Fi, MPLS
• D.The TCP/IP Internet layer maps to OSI Layer 5 (Session); protocols: NetBIOS, RPC, TLS
