Question

How does the kernel ensure that a thread has no idea that it was ever interrupted?

a.

By storing the state of all CPU registers before suspending the thread and restoring that state when the thread is resumed

b.

By blocking the thread when its quantum is up

c.

By terminating the thread when its quantum is up

d.

By lowering the thread's priority when its quantum is up
