Consider a three sequentially stepped process named as Process A$,$ Process B$,$ and Process C$.$ Input comes into Process A$.$ Output from A goes into Process B$.$ Output from $B$ goes into Process $C.$ Output of $C$ is the final output. Suppose the cycle time of each is: A $-2$ minutes per unit, $B-3$ minutes per unit and $C-1$ minute per unit. Process A receives input at the rate of $30$ per hour. Which process$($es$)$ will be experiencing starving?
