Solution

The correct option is B $R_{1}$ and $R_{2}$ only
$\begin{matrix} I n s t e a d y p o t e n t i a l d i f f e r e n c e a c r o s s c a p a c i t o r V_{2} = p o t e n t i a l d i f f e r e n c e a c r o s s r e s i s tan c e R_{2} = (\frac{R_{2}}{R_{1} + R_{2}}) V H e n c e, V_{2} d e p e n d s u p o n R_{2} a n d R_{1} \end{matrix}$
Hence, option $B$ is the correct answer.
