Verified Correct Answer: B.
Physical Principles & Numerical Solution
When a magnet is moved near a ferromagnetic material like soft iron, it induces magnetism in the material. The end closer to the magnet becomes the opposite pole.
In this scenario, the south pole of the magnet X approaches point P. Point P becomes a north pole to repel the south pole, while the opposite end (Q) becomes a south pole.
