The answer for this is 6v. Because it's in parallel and for those who are saying the capacitor is connected to a dc supply, yes the capacitor behaves as an open circuit when connected to DC and due to infinite resistance all of the 6 volts are dropped across it.

I, from the question, it is evident that capacitors are in parallel, then voltage will be same in each branch (ie, in each capacitor).
II, it is also evident that the supply source is DC, for a DC supply capacitor act as an open circuit.
(if there is any open in a circuit then the supply voltage will be available across the 'open' without any drop).
So, here the voltage across two branches (ie, across two capacitors) are equal as supply.
So, answer is 6V.
