Which command is used for managing processes in Linux?

The correct answer encompasses all the options provided because each one plays a significant role in process management in Linux.

The command 'ps' is used to display information about the currently running processes. This command provides a snapshot of all running processes, including their process IDs (PIDs), and allows users to see what is currently active on the system.

The 'top' command offers a dynamic real-time view of the processes running on the system. It updates continuously, allowing users to monitor CPU and memory usage, identify which processes are consuming resources, and manage those processes interactively. Users can send signals to processes directly from the 'top' interface.

The 'kill' command is used to terminate processes by their process ID. It sends signals to processes, allowing users to stop or otherwise manage them. This is crucial for controlling misbehaving processes that may need to be forcibly terminated.

Since all these commands serve distinct yet complementary roles in handling and monitoring processes, the option that includes all of these commands accurately represents the various tools available for process management in Linux.
