Which of fall is state diagram for Mealy machine shown :–

A synchronous state machine is created with a state diagram as given below. The output of this circuit is taken from the LSB of the 3-bit counter which is formed based on the state table. If the output is plotted for the first 5 clock pulses after the machine was started from state ‘0’, then the output unipolar waveform will look like
