I think maybe (c). 9 ohms because starting from A if we see the resistances the branch that divides from A has a parralel connection with each other then the same pattern is followed thrice so when we consider the upper branch the resistance is 3+3=6and then both upper and lower branch is parralel ie 1/r=(1/6)+(1/6) r=3 then same thing thrice so total r =3+3+3=9
