Explanation

NetBIOS Enumerator (B) is a dedicated tool designed specifically to query and extract NetBIOS information from Windows systems - including hostnames, MAC addresses, logged-in users, and shared resources - making it the purpose-built choice for this task.

Why the distractors are wrong:

• Wireshark (A) is a packet capture/network traffic analyzer - it can see NetBIOS traffic passively, but it's not an enumeration tool.
• Netcat (C) is a general-purpose TCP/UDP networking utility used for port scanning and raw connections, not NetBIOS-specific enumeration.
• Snort (D) is an intrusion detection/prevention system (IDS/IPS) - it monitors and alerts on traffic, not enumerates targets.

Memory tip: The name gives it away - when a tool is literally called "NetBIOS Enumerator," it enumerates NetBIOS. On CEH/Security+ style exams, the most specifically named tool for a task is almost always the correct answer over general-purpose tools like Wireshark or Netcat.
