💡 Solution & Explanation

A colloidal solution as a whole is electrically neutral because the charge on the dispersed phase particles is exactly balanced by an equal and opposite charge in the dispersion medium. Statement II is also a true fact, as mutual repulsion of similarly charged dispersed particles prevents coagulation and provides stability. However, this mutual repulsion does not explain the overall electrical neutrality of the entire solution. Therefore, correct answer is B.
