Correct Answer: B সঠিক উত্তর: B

Explanation ব্যাখ্যা

Soaps are essentially salts of fatty acids, created through a process called saponification, where fats and oils react with a strong base like sodium hydroxide or potassium hydroxide. These fatty acid salts have a unique structure that allows them to interact with both water and oil, effectively trapping dirt and grease particles in micelles, which can then be rinsed away.
