Option D
(a) Mixture A i.e., Iron And Sulphur is heterogenous Mixture.
(b) Iron Sulphide is Homogenou Compund
(c) As Iron And Sulphur are hetero Genous Iron Gets Separated from Sulphute and Clings To the Bar Magnet
(d) As it is a Homogenous Compund Fe cannot be Extracted From Iron Sulphide By Physical Means of Magnetic Attraction. So Iron In Compund B Does not clings to bar magnet
