Hii 
A and B end are open , so, there will be no current through outer 2ohm and 2 ohm resistence , 
Current will only flow in the inner closed part , 
Let assume current = I amp , and apply Kvl in inner loop , you will get the value of I  through 4 ohm .

The correct answer will be 9/8 A .
Use the equivalent circuit for battery and 4ohm resistance by formula (E1r2+E2r1)/(r1+r2)
Here E1 is 4V and E2 is zero
