B
Correct answer
Explanation
The 'w' command shows who is currently logged into the system and what they are doing (including their current command and CPU usage). The 'whoami' command only shows your own username, 'telnet' is for remote connections, and 'finger' provides user information but not real-time activity.
AI explanation
The w command displays who is currently logged into the system along with what each user's process is currently running, combining the output of who with process/load information. whoami only shows the current user's own username, finger shows details about a specific user rather than a live activity summary, and telnet is a remote connection tool, not a status command.
