What is the importance of micelle formation in the cleansing action of soap?

Correct answer: It helps trap dirt inside and disperse it in water

The governing concept is micelle formation by amphiphilic soap molecules. In water, their hydrophobic hydrocarbon tails point inward and attach to oily dirt, while their hydrophilic ionic heads point outward toward water. This arrangement encloses grease in a dispersed droplet. Agitation breaks the dirt into smaller suspended particles, which can then be carried away during rinsing. Therefore option A correctly explains cleansing; the other options describe impossible changes.
