Show answer and explanation

Answer: B. The distance between an iron object and magnet is more

B. The distance between an iron object and magnet is more: Magnetic force is a non-contact force that acts through a magnetic field. The strength of this field decreases rapidly as the distance from the magnet increases. Since Meera is in the dining room and Shirish is in the bedroom, the distance between them is too great for the magnet's field to exert a noticeable pull on the iron object.
