To determine which of the following is a passive footprinting tool, we need to understand what passive footprinting means. Passive footprinting refers to the collection of information about a target without directly interacting with it or raising any alarms.

Now, let's examine the options provided and determine which one fits the criteria of a passive footprinting tool:

1. Nmap: Nmap is an active footprinting tool that actively scans and probes a target's network to gather information. It sends packets to the target, which can be detected and potentially raise alarms. Therefore, Nmap is not a passive footprinting tool.

2. Wireshark: Wireshark is a network protocol analyzer that captures and analyzes network traffic. It can be used for passive footprinting by capturing and examining network packets without actively interacting with the target. Therefore, Wireshark can be considered a passive footprinting tool.

3. Nessus: Nessus is a vulnerability scanner that actively scans a target's system for vulnerabilities. It sends packets and probes the target, which can be detected and raise alarms. Therefore, Nessus is not a passive footprinting tool.

Based on the above analysis, the correct answer is option 2: Wireshark.
