D the object must have different temperatures
Pressure and heat. I hope this helps
There is a low correlation between the independent and dependent variables. Something we are not considering is probably causing the changes in the dependent variable.
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
