Solution

The correct option is C During the process a work is done by the external force F
As the capacitors are connected to the battery, total potential difference between the capacitors will remain same. Thus there is no change of internal energy of battery during the charging process. As A is connect to the positive end of battery so the charge will flow from A to B to maintain constant potential. As the capacitors are in series so the final charge on A and B are equal and it is equal to the equivalent charge. As the charge is flowing so a work is done by the external force F.
