Multiple choice Easy world-modelplanning ~50s

Your agent's LearnedWorldModel has never tried moving left from cell (2,3). During planning, A* calls predict((2,3), 'left'). What happens?

A It returns each neighbouring cell with probability 0.25, and A* plans over the average of those outcomes B It returns None, and A* skips that move: it can only plan through transitions the agent has experienced C It returns (2,3) unchanged, so A* treats the move as a harmless bump into a wall and carries on D It returns the outcome seen for 'left' from the nearest cell it has tried, since neighbouring cells behave alike

Hints are free to take and they are counted. A correct answer after two hints moves your mastery less than one without — which is the honest way to score it.
