its clearly B. although the box itself experiences no change in momentum the speed at which the portal envelops the box imparts an apparant momentum to the room, from the frame of reference of the box.
The box cant emerge from the portal traveling at X km/h relative to the room and then just stop, momentum must be conserved.
and speaking of energy being conserved, this implies that the portal encounters resistance as it envelops the cube proportional to the square of the speed at which the cube is enveloped * the mass of the cube
