While doing fast scan using F option, which file is used to list the range of ports to scan by nmap?

A.
services

B.
nmap-services

C.
protocols

D.
ports

Explanation:
Nmap uses the nmap-services file to provide additional port detail for almost every scanning method. Every time a port is referenced, it’s compared to an available description in this support file. If the nmap-services file isn’t available, nmap reverts to the /etc/services file applicable for the current operating system.
