To answer your question accurately, I would need to reference the specific distances shown in the picture regarding paper clips W, X, Y, and Z and their movement toward the magnet. Since I can't see the image, I can only guide you based on the information provided.
If you know the distances at which W and X moved toward the magnet, you can determine the correct answer by identifying the distance beyond which the other paper clips (Y and Z) did not move. The answer would be the closest distance that W and X moved toward the magnet while Y and Z did not.
Assuming you can identify which paper clips moved and at what distance, choose the option that corresponds to a distance greater than the one at which W and X started moving but shorter than or equal to the distances for Y and Z, as those two did not move.
Feel free to provide more details or specify the distances shown in the image to get a more precise answer!
