During the cleaning action of soap ____ part of soap dissolves in the dirt and encapsulates to form micelle 

During cleaning, the hydrophilic heads face towards the surrounding water and the hydrophobic tails attach themselves to the dirt and remove it from the cloth. Due to this arrangement of hydrophilic and hydrophilic part, a spherical aggregate of soap molecules is formed in the soap solution in water known as micelle. 

Thus, during the cleaning action of soap, the hydrophobic part of soap dissolves in the dirt and encapsulates to form micelle.

Hence, option (C) is correct.
