Which one of the following is the correct sequence of the different states of a process in process management function of an operating system ?

In Operating Systems, a process moves through various states during its lifecycle, commonly described by the 5-state model:

• New: The process is being created.
• Ready: The process is admitted and waits in the ready queue for CPU allocation.
• Executing (Running): The CPU is executing the process's instructions.
• Waiting (Blocked): The process is waiting for an I/O event or signal.
• Terminating: The process has finished execution.

A process must be admitted to the Ready state before it can execute or wait for I/O. Therefore, Option A (New, Ready, Waiting, Executing, Terminating) represents a logically possible chronological sequence of states a process may pass through. Option B is incorrect because a process cannot transition directly from 'New' to 'Waiting' without first being admitted to the system (Ready) and dispatched to the CPU (Executing).
