Consider the branch A-C which has the battery.
Now, potential difference across the battery (assuming it is ideal and has no internal resistance) = 2V
This is also equal to Va - Vc. (which are the two terminals across which the battery is connected)
Thus Va - Vc = 2V

@FoolAroundMath  : Exactly that's the thing that i did! .. So, you mean the ans is 2V itself.. no ?.. Thanx! :)
