Correct Option (3)  ) Zone electrophoresis is used to separate colloidal particles based on their charge.

Zone electrophoresis is a technique used to separate charged molecules or particles based on their electrophoretic mobility. The sample is applied as a thin layer on a support medium, such as a gel or paper strip, and is then subjected to an electric field. The sample will migrate and separate into different zones based on their mobility. Therefore, statement 3 is true. However, statement 1 is false because zone electrophoresis is not a type of paper chromatography technique. Thus, statement 2 is also false. Therefore, the correct answer is 3.
