Answer
a). 5 ohm resistance has largest current since all current passes through it whereas it splits in the ratio 1:2 while passing through the 2 ohm and 1 ohm resistances.
b). 5 ohm resistance will have highest voltage across it since $I(R+R')=V$, R=5 ohm , R' = 2/3 ohm
c). Power = $I^{2} R$ so 5 ohm resistance will have largest power output.
