A shift-left Shift Register (SR) and a D flip-flop are connected to a synchronized clock as shown in the figure. Assume that the SR and D flip-flops are initially cleared and the XOR gate has no propagation delay.
Which of the following options gives the correct binary representation \(b_7b_6b_5b_4b_3b_2b_1b_0\) of the content of the shift register immediately after the \(5^{th}\) clock transition (positive edge)?
