Displays a list of users who are logged on to remote machines or machines on local network.

• A. rusers
• B. rwho
• C. who
• D. finger

Answer: (A)

The key idea is finding a command that shows who is logged into systems across the network, not just on the local machine. rusers is designed to query the machines on the local network and display the users currently logged into those remote hosts. That network-wide visibility is what makes it the best fit for listing remote users across multiple machines. In contrast, who shows only who is logged into the current machine, and finger provides user-specific details (often about a single user on a single host) rather than a network-wide listing. rwho is similar in spirit to rusers but is older and less commonly used today. So the option that aggregates remote login information across the local network aligns with rusers.
