An electrolytic capacitor between the power transformer and the rectifiers in a power supply:
A provides that earth ground be isolated from DC ground
B is part of a voltage doubler circuit
C eliminates the need for filter capacitors
D protects the diodes from power surges

BUT im actually completing the test. I have like 70 questions to go.Im not too good when it comes to hardware lol

lol, thats true!

the inline cap keeps the ac incoming voltage at a steady level so the rectifier can create more stable dc! lol

I'm fairly sure that some of the questions in this practice exam are actually wrong. or at least misleading.

I'll keep looking when I actually get to work and post my score later I think

I got 88% (it's been a long time since I studied electronics).

as I said, I think that some of the questions are a little misleading.
one of them I know for sure that the answer that they give is wrong.
