A,B,D
Final pressures should be equal.
and apply PV=constant for both compartments

Pressure will be same because you want the wall to be at rest and not accelerating..

So if the volume is x on the Left side while it is 3V-x on the right side..

Also, on the left side,

P1.x=PV

P1.(3V-x)=2P.2V

Dividing, we get 4x=3V-x

so x= 3/5V

Pressure is 5/3P
