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.

Regulator (sewer) , a control device used in a combined sewer system and The devices which converts the pulsating DC into pure DC is called filter so this is simple to us the answer is filter.

As per my knowledge, filter is the right answer because after regulated voltage some ac component present in that remove with filter section only.

I think Filter is the answer.

Transformer generates higher voltage with out any change in frequency. Rectifier converts half of the AC into DC. Filters are used to remove unwanted material.

I think it is oscillator.
