Best answer
The correct choice is (d) bridge wave rectifier

To elaborate: The bridge rectifier provides a full wave pulsating dc. Due to the inertia of the movable coil, the meter indicates a steady deflection proportional to the average value of the current. The meter scale is usually calibrated to give the RMS value an alternating sine wave input.
