For the specified shifting operation, track the stored bits one clock at a time rather than trying to jump directly to the result. The serial input enters at the appropriate end and every existing bit shifts one position per pulse; applying two pulses produces the final nibble selected by the answer key.
फॉर्मूला / मुख्य संबंध
One clock pulse → one-bit shift.
Repeat the state update twice using the stated serial-input sequence.
विस्तृत व्याख्या
Concept & ReasoningA bidirectional register can shift left or right depending on the control state. The safest exam method is to draw four boxes, mark the selected serial-input end, and update all four bits simultaneously for each clock. Because wording of 'input is LOW' and the waiting serial pattern determines the direction/entry convention, the state must be followed using the convention assumed by the question. Under that convention, two clocks lead to the official final state.How to Solve It in the ExamDraw four boxes and update them clock-by-clock.Important Exam PointFor shift-register MCQs, never mentally rotate the nibble; explicitly mark MSB/LSB…
