Coagulation and flocculation are two different processes that are used to destabilize a colloid. Coagulation is the process of destabilizing a colloid by adding an electrolyte. The electrolyte neutralizes the charge on the colloidal particles and causes them to come together to form aggregates that are large enough to settle under gravity. On the other hand, flocculation is the process of bringing together destabilized colloidal particles to form a floc. Flocculation involves the addition of a flocculating agent that causes the destabilized particles to come together and form larger, easily settleable aggregates called flocs. Therefore, option A is the correct answer.
