The answer should be water molecules still move between two solution, but no net movement.

Osmotic equilibrium means where two solution has reached the same amount of water potential because of the osmosis before, they have the same solute concentration now.

Always remember that water molecules still move in all solutions, but just that since there's no more concentration difference, the water molecules that move from right to left and left to right is equal. Therefore there's no net movement.
