Thanks bro. Useful approach.

If the mux input are inverted like I3 I2 I1 I0. then what will be the answer. I mean, Does order matters??

---

@muthu kumar     yes bro ,it really matters .answer will be changed . according to selection lines in a mux we select the input . if mux input are inverted like i3,i2,i1 and i0. the characteristics equation will be changed

Ok, then Equation for MUX will be like A'C'I3 + A'CI2 + AC'I1 + ACI0 ..is it crct?

---

A more easier approach will be Reduce the function with K-Map and write the equation of mux in terms of A,C,IO,I1,I2,I3 now check for the options you will get D as correct

reducing the function by k-map will fetch you A'B'+C
