C) True
D) Blocking one kernel level thread blocks all related threads is false, because kernel level threads are independent.
Context switch time is longer for kernel level threads than for user level threads.
User level threads do not need any hardware support.
Related kernel level threads can be scheduled on different processors in a multi-processor system.
Blocking one kernel level thread blocks all related threads.
