Solution
The correct option is B Handpicking ∙ Handpicking is used for separation when the differences between the components are clearly visible. These differences can be color, size and shape. Also, the particle size should be large enough to be hand-picked.
∙ Ram can hand pick candies of red colour because they can be easily differentiated from the candies of other colours.
