Which command line switch would be used in NMAP to perform operating system detection?

The correct answer is D. -O. In Nmap, the -O flag enables OS detection by analyzing TCP/IP stack fingerprinting responses from the target. '-OS' is not a valid Nmap switch. '-sO' performs an IP protocol scan (not OS detection). '-sP' (now deprecated in favor of -sn) is a ping scan used for host discovery. On

Explanation

In Nmap, the -O flag enables OS detection by analyzing TCP/IP stack fingerprinting responses from the target. '-OS' is not a valid Nmap switch. '-sO' performs an IP protocol scan (not OS detection). '-sP' (now deprecated in favor of -sn) is a ping scan used for host discovery. Only '-O' correctly triggers OS fingerprinting in Nmap.
