signals X and Y for the adder in ALU and the "incoming" carry C$0.$ As an example, multiplexers controlling the X$0,$ Y$0$ bits and the C$0$ control signal are given. What operation will the adder perform in the ALU if the code $00100$ is sent to the control inputs s$4...$s$0?$

The s$4$ and s$2$ bits are more significant.
