(A) Let us analyze the potential at different points in the circuit.Starting from the leftmost wire,let the potential be $0 	ext{ V}$.Moving across the top branch,the potential changes by $2 	ext{ V}$ at each battery. Similarly,for the bottom branch,the potential changes by $2 	ext{ V}$ at each battery.For the first vertical resistor of $1 \Omega$,the potential at the top node is $0 	ext{ V} - 2 	ext{ V} = -2 	ext{ V}$ and at the bottom node is $0 	ext{ V} - 2 	ext{ V} = -2 	ext{ V}$.The potential difference across this resistor is $(-2 	ext{ V}) - (-2 	ext{ V}) = 0 	ext{ V}$.Similarly,for the second vertical resistor,the potential at the top node is $-2 	ext{ V} - 2 	ext{ V} = -4 	ext{ V}$ and at the bottom node is $-2 	ext{ V} - 2 	ext{ V} = -4 	ext{ V}$.The potential difference is $(-4 	ext{ V}) - (-4 	ext{ V}) = 0 	ext{ V}$.For the third resistor,the potential at the top node is $-4 	ext{ V} - 2 	ext{ V} = -6 	ext{ V}$ and at the bottom node is $-4 	ext{ V} - 2 	ext{ V} = -6 	ext{ V}$.The potential difference is $(-6 	ext{ V}) - (-6 	ext{ V}) = 0 	ext{ V}$.Since the potential difference across each resistor is $0 	ext{ V}$,the current flowing through each resistor is $I = V/R = 0 	ext{ V} / 1 \Omega = 0 	ext{ A}$.
