The figure shows the ALU part used to shift the $4-$bit word given as the argument A $($A$3...$A$0),$ and the condition bit C$.$ The task is performed by multiplexers that shape the appropriate output bits X$3...$X$0$ and the output form of the condition C $-$ Cout. The multiplexers are controlled by the control word s$2...$s$0.$

What shift operation will be performed by the ALU if the code $010$ is given to the control inputs s$2...$s$0?$
