The correct explanation for the answer is option 1: Micelle. When soap or detergent is mixed with water, it forms tiny structures called micelles. Micelles are formed because soap and detergents have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail.

In the water, the hydrophilic heads of the soap molecules are attracted to the water molecules, while the hydrophobic tails are repelled by water and try to stay away from it. This leads to the formation of micelles, where the hydrophilic heads face outward towards the water and the hydrophobic tails cluster together in the center of the micelle, away from the water.

These micelles have the ability to trap and suspend dirt, grease, and oil particles in the water. The hydrophobic tails of the micelles surround the dirt particles, while the hydrophilic heads remain attracted to the water. This allows the dirt particles to be easily washed away when the water is rinsed or agitated.

Overall, the formation of micelles helps soap and detergent molecules to effectively clean by removing dirt, grease, and oil from surfaces and keeping them suspended in water for easy rinsing.
