    A)
    P Q R S
    Sublimation Magnetic Filtration Evaporation

    B)
    P Q R S
    Magnetic separation Filtration Sublimation Evaporation

    C)
    P Q R S
    Evaporation Magnetic separation Evaporation Filtration
                   

    D)
    P Q R S
    Sublimation Magnetic separation Evaporation Filtration

    Correct Answer: A

    Solution :

              Camphor being sublimable in nature, is separated by sublimation (process in which solid is directly converted into vapours on heating). Iron being magnetic in nature, is separated by magnetic separation method. Sand particles being large in size and insoluble in water are separated by filtration. They are obtained in the filter paper.      On evaporating the filtrate, salt is separated.
