Consider the following table$-$
Column-$I$ Column-$II$
$(A).$ Best and latest technique for isolation,purification and separation of organic compounds $(i).$ Chromatography
$(B).$ In Lassaigne's test for $N$ $(ii).$ Vacuum distillation (distillation under reduced pressure)
$(C).$ In Lassaigne's test for $S$ $(iii).$ Violet coloured complex is formed
$(D).$ Aniline is purified from water by $(iv).$ Prussian blue coloured complex is formed
$(E).$ Glycerol is purified from spent lye $(v).$ Steam distillation

The correct match is $-$

  • A
    $A-i, B-iv, C-iii, D-v, E-ii$
  • B
    $A-iv, B-v, C-iii, D-ii, E-i$
  • C
    $A-i, B-iv, C-iii, D-v, E-ii$
  • D
    $A-v, B-iii, C-iv, D-ii, E-i$
