A `10muF` capacitor and a `20muF` capacitor are connected in series across a 200 v supply line. The charged capacitors are then disconnected from the line and reconnected such that those same polarities are connected to each other and no external voltage is applied. The potential difference across capacitors is

A

`(800)/(9) ` volt

B

`(800)/(3) ` volt

C

`400` volt

D

`200` volt
