Solution

The correct options are
B 0.2 A current flows in G.
C Potential difference across C1 is 1V.
D Potential difference across C2 is 1.2V

As direct current doesnot flow through capacitor, current in the circuit can be considered as shown in figure.
From kirchhoffs law
i=24+1+5=0.2
Potential across C1=VAB+VBC=0.2(4)+0.2(1)=1 V
Potential across C2=VCD+VBC=0.2(5)+0.2(1)=1.2 V
