Explanation

Nmap (Network Mapper) is the industry-standard tool for port scanning - it probes target hosts to discover open ports, running services, and OS fingerprints, making it a staple of penetration testing reconnaissance. Aircrack-ng (A) is a wireless network security tool focused on cracking Wi-Fi encryption, not port scanning. Tracert/traceroute (B) traces the network path between two hosts hop-by-hop but tells you nothing about open ports on a target. Wireshark (D) is a packet capture and protocol analysis tool - it inspects traffic that's already flowing past your interface rather than actively probing targets.

Memory tip: Think "N-map = Network Map" - it literally maps out what's open on a network, which is exactly what a port scanner does.
