Which command displays the current status of a service?

The command that displays the current status of a service is indeed "service status." This command is commonly used in systems that use the System V init or systemd service manager. When executed, it provides valuable information about a particular service, such as whether it is running, stopped, or in a failed state. Additionally, it may show the process ID associated with the service, the memory and CPU usage, and other relevant status details. This information is crucial for system administrators who need to monitor and manage services effectively on a Linux system.

The other options do not correspond to valid commands found in typical Linux environments.
