Solution
The correct option is Aevaporation A mixture of glucose water can be separated by the method of evaporation. Water being a volatile substance will evaporate and glucose will be left behind.
Handpicking or winnowing is done when the differentiation between the particles can be done on basis of their appearance i.e. colour, shape, weight or size. Glucose and water cannot be separated by these methods as they form a homogenous mixture and cannot be separated based on their appearance.
