Study the log below and identify the scan type.

The -sR flag performs an RPC scan to identify RPC-based services on open ports, which would show RPC program data rather than IP protocol numbers.

The -sS flag performs a TCP SYN (half-open) scan, which would log TCP port states (open, closed, filtered) rather than IP protocol responses.

The -sV flag performs service and version detection against open ports, which would log service names and version strings rather than raw protocol numbers.

The -sO switch instructs nmap to iterate through IP protocol numbers (0-255) and send raw IP packets to determine which protocols the target host responds to, producing output listing protocol numbers rather than port numbers. The -T flag sets the timing template, controlling scan aggressiveness and packet rate. This scan type produces a log showing protocol IDs rather than port states, which is the distinguishing characteristic of the observed log.
