Why each option
A Linux daemon is a long-running background process that is a child of the init process, providing system services without a controlling terminal.
This describes a malicious or resource-abusive process, not the standard definition of a daemon.
Daemons are long-running background processes that are children of the init process (PID 1 or systemd). They are typically started at boot time and run continuously to provide system services such as networking, logging, or scheduling, detached from any controlling terminal.
A process with no parent is called an orphan or zombie process, not a daemon.
CPU starvation describes a scheduling problem where a process cannot obtain CPU time, which is unrelated to what a daemon is.
