In the circuit shown in the figure, there are two
P parallel plate capacitors each of the capacitance \( C \).

W The switch \( S_{1} \) is pressed first to fully charge the capacitor \( C_{1} \) and then released. The switch \( S_{2} \) is then pressed to charge the capacitor \( \mathrm{C}_{2} \). After some time, \( S_{2} \) is released and then \( S_{3} \) is pressed, After some time,
(A) the charge on the upper plate of \( \mathrm{C}_{1} \) is \( 2 \mathrm{CV}_{0} \)
(B) the charge on the upper plate of \( \mathrm{C}_{1} \) is \( \mathrm{CV}_{0} \)
(C) the charge on the upper plate of \( \mathrm{C}_{2} \) is 0 .
(D) the charge on the upper plate of \( \mathrm{C}_{2} \) is \( -\mathrm{CV}_{0} \)
