Which component is used to change alternating current to direct current? a diode an integrated circuit a transistor a capacitor

As we know that equivalent resistance of a capacitor for an AC circuit is given as

so here for an AC circuit capacitor will provide less resistance to AC component of the current

While for DC as we know it has ZERO frequency

so we will have large resistance

so here we will have to use capacitor as a filter circuit which will separate AC component of current from the DC current

So correct answer will be

CAPACITOR

nah.   i'm just sleepy.
