Final answer:
The false option is c) Related kernel level threads can be scheduled on different processors in a multiprocessor system
Step-by-step explanation:
The correct option that is false is c) Related kernel level threads can be scheduled on different processors in a multiprocessor system. Kernel-level threads are managed by the operating system, and they usually run on a single processor or core. User-level threads do not have direct hardware support, so they rely on the operating system and kernel-level threads for execution. Context switch time is longer for kernel-level threads compared to user-level threads because it involves a higher overhead.
