Match column $-I$ and column $-II$ with the correct relation:

Column $-I$	Column $-II$
$(i)$ Liquid boiled at low temperature	$(a)$ Fractional distillation
$(ii)$ Glycerol from lye	$(b)$ Simple distillation
$(iii)$ The liquid with lower boiling point condenses first	$(c)$ Steam distillation
$(iv)$ The liquid with higher boiling point condenses first	$(d)$ Distillation under reduced pressure

(A) The correct matches are:
$(i)$ Liquid boiled at low temperature is achieved by $(d)$ Distillation under reduced pressure.
$(ii)$ Glycerol from lye is purified by $(c)$ Steam distillation (or distillation under reduced pressure,but in standard contexts,it is associated with distillation under reduced pressure; however,given the options,$(c)$ is often used for volatile substances,while $(d)$ is specific for heat-sensitive liquids like glycerol).
$(iii)$ The liquid with lower boiling point condenses first in $(b)$ Simple distillation.
$(iv)$ The liquid with higher boiling point condenses first in $(a)$ Fractional distillation.
Thus,the correct sequence is $(i-d), (ii-c), (iii-b), (iv-a)$.
