Solution

The correct options are
B The anions to form the clusters of colloidal dimension
C The polar ends forming the clusters are directed towards water
Soaps are sodium (or potassium) salts of higher fatty acids which contain more than 12 carbon atoms.
The option B and C are the correct answer and the options A and D are incorrect answers.
(A) The cations do not associate to form the aggregates.
(B) The anions to form the clusters of colloidal dimension. They form small emulsified oil droplets in water.
(C) The polar ends forming the clusters are directed towards water. The polar ends are hydrophilic and water soluble.
(D) The non polar (Hydrocarbon) ends are directed towards oil. They are hydrophobic and oil soluble.
