Answer #1

Correct option E ( None of these )

We know the formula for capacitance is

where Q is charge and V is potential difference but it doesn't mean that capacitance depends on the charge and potential difference.

Actually capacitance depends on the geometry of conductors for example you see the formula of a parallel plate capacitor , spherical capacitor or a cylinder capacitor all are different but none of them includes charge or potential difference.

In a nutshell - capacitance depends on the geometry , on the system of arrangements
