Dc power supply with their basic parts.
Rectifier - converts sine wave input to pulsating DC output
Filter - smoothen the output of the waveform/reduce fluctuations
Regulator- provides constant/dc voltage and also maintains the output voltage at any load.
Load- recipient of the voltage
So, the answer is filter not a regulator.

I think Filter is the answer.

The regulator provides the Smooth DC voltage which is fixed.
The output of bridge rectifier is pulsating DC signal.
The capacitor is used as a filter to remove the ripple factor.

Filter O/P is pulsated DC And Regulator O/P is pure DC.

According to my knowledge its B- filter because as it removes DC ripples which were already converted from ac to dc at diode.

No I strongly said Regulator because after filtering it have some ac.

Regulator is used to adjust the output voltage, it is the filter which smoothness the DC. Consider LM7805 it maintains a constant DC voltage according to knob adjusted it acts as a rheostat.

Rectifier provides unidirectional o/p which can also be said pulsating DC. Now this is given to filter which gives fluctuating DC. Let us say if I am expecting 9v DC then after filtering I may be getting voltage ranging from 9v to 11v or now by using any voltage regulator IC like IC7809 I get pure and smooth dc of 9v.

Transformer : Give us AC sinusoidal wave form.
Rectifier : Convert AC into pulsating DC.
Filter : Convert Pulsating into ripples or approximate pure DC.
Regulator : Just regulate output DC voltage.

Regulator is a circuit that maintains a constant dc voltage filter eliminates the fluctuations in the rectified voltage & produced relatively smooth dc voltage.
