Answer» Correct Answer - A::D Adsorption of the same type of ions on the surface of the colloidal particles causes repulsion in the ions and thus stabilise the colloid. Therefore (a) is correct option. The potential difference between fixed and diffused layers of oppositely charges is responsible for the s yability of colloid.
