Which NMAP flag enumerates valid protocols on a target?

Explanation:
IP protocol discovery is what this tests. The -sO option performs an IP protocol scan to determine which IP protocols the target will respond to. It sends packets with different IP protocol numbers and watches how the host replies (or doesn’t) to deduce which protocols are supported or allowed by the target’s network stack and firewall. This can reveal protocols like TCP, UDP, ICMP, and others that the host will handle, giving you a snapshot of the target’s IP layer capabilities. Other options serve different purposes, such as discovering live hosts, detecting the operating system, or probing ports, but they don’t specifically enumerate supported IP protocols.
