A Boolean digital circuit is composed using two 4-input multiplexers (M1 and M2) and one 2-input multiplexer (M3) as shown in the figure. X0–X7 are the inputs of M1 and M2 and can be set to 0 or 1. The select lines of M1 and M2 are $(A,C)$, and the select line of M3 is $B$. The output of M3 is the final circuit output. 
Which one of the following sets of values of $(X0,X1,X2,X3,X4,X5,X6,X7)$ will realise the Boolean function \[ F(A,B,C) = \overline{A} + \overline{A}C + ABC \; ? \]
