Two multiplexers are connected as shown below. The inputs $(A,B,C$ and the output $F$

are $4-$bits and $(D$ and $E)$ are one$-$bit. The numbers inside the multiplexers correspond to

the value of the selectors $D$ and $E$ which will decide which input $A,B$ or $C$ will pass to

the output $F($For example, If $D=0$ and $E=0$ then $C$ will be selected to pass to $F).$
