The fragrance of flowers is due to the presence of some steam volatile organic compounds called essential oils. These are generally insoluble in water at room temperature but are miscible with water vapour in vapour phase. A suitable method for the extraction of these oils from the flower is
(a)
distillation
(b)
crystallization
(c)
distillation and reduced pressure
(d)
steam distillation
