Multiple choice

For the circuit shown in figure below, two 4-bit parallel-in serial-out shift registers loaded with the data shown are used to feed the data to a full-adder. Initially, all the flip-flops are in clear state. After applying two clock pulses, what will be the outputs of the full-adder?

  1. S = 0, C0 = 0

  2. S = 0, C0 = 1

  3. S = 1, C0 = 0

  4. S = 1, C0 = 1
