While performing a security audit, an administrator discovers that a machine is accepting connections on TCP port 184, but it is not obvious which process has the port open. Which of the following…

`traceroute` maps the network path to a destination and does not show local port usage or the processes holding them.

`strace` traces system calls and signals of a process, useful for debugging a running process, but not for identifying an unknown process listening on a port.

`debug` is a generic term and not a specific Linux command for this task.

`nessus` is a vulnerability scanner, used for identifying security flaws, not for directly identifying the local process holding a specific open port.

The `lsof` (list open files) command can display information about files opened by processes, including network sockets. Using `lsof -i :184` will precisely show the process ID (PID) and command name of the process that has TCP port 184 open and is currently accepting connections.
