B would be correct if this existed in real life and had to be compatible with general relativity. If we took this exact same setup and moved it into space, how could you tell if the cube is moving towards the portal or the portal is moving towards the cube? You also can’t use the blue portal as a reference point since it could also be moving independantly from the orange portal.
Correct.
It’s like dropping a hula hoop over it in this scenario. There is nothing to generate its motion.
Using portals rules yeah A is the correct answer.
