Solution

The correct options are
C Size of the plates
D Separation between the plates
The capacitance is given by
C=εAd
It only depends on ε of the medium, Area of the plates and separation between plates.
Even though, we have an equation that says, C=QV
In that equation, C is a constant. i.e., Q and V will always change by the same factor and cancel out. Therefore it doesn’t depend on the charge on the plates or the potential difference between them.
