When a process is in a "Blocked" state waiting for some I/O service. When the service is completed, it goes to the __________

A) Running state

B) Ready state

C) Suspended state

D) Terminated state

Correct Answer : Ready state

Explanation : Suppose that a process is in “Blocked” state waiting for some I/O service. When the service is completed, it goes to the ready state. Process never goes directly to the running state from the waiting state. Only processes which are in ready state go to the running state whenever CPU allocated by operating system.
