In a balanced circuit, the impedance of the two arms of the circuit (R2 and R3 in this case) are the same. Therefore, the voltage drop across each arm is equal and the voltage at the midpoint of the circuit (point A) is at ground potential. As a result, there is no voltage across the load (R4) and hence no current flows through it. Therefore, the correct choice is D, no current through the load.
