A Correct answer
Explanation

Nmap (Network Mapper) is the standard tool for port scanning and network discovery. It can identify open ports on a target system. Wireshark (formerly Etherial) is a packet analyzer for capturing and examining network traffic, not primarily for port scanning. 'Switch sniffer' is a generic term, not a specific tool.
