Best answer
Right choice is (b) Agitation

Explanation: Agitation is the process involving induced circular motion of homogeneous particles to prepare a liquid mixture, mechanically. Sedimentation refers to the settling down of suspension particles whereas Mixing refers to the random distribution of initially separate ingredients. Crystallization on the other hand is the formation of clumps of solid particles due to mass transfer.
