In the circuit shown below, the input voltage is sinusoidal and \(2.5~\text{V}\) peak-to-peak. The capacitors are \(20~\mu\text{F}\) each. Assume ideal diodes (zero knee voltage) and \(R_L\) is very large (almost infinite). Which one of the following options is \emph{closest to the peak-to-peak voltage across \(R_L\), after a large number of cycles?}
