Solution
The correct option is A Both capacitor or inductor
The rectified voltage is in the form of pulses of the shape of half sinusoids.
Though it is unidirectional, it does not have a steady value.
To get steady DC output from the pulsating voltage, normally a capacitor is connected across the output terminals (parallel to the load).
One can also use an inductor in series with the load for the same purpose.
Since these additional circuits appear to filter out the AC ripple and give a pure DC voltage, so they are called filters.
Hence, option (C) is the correct answer.
