Solution
The correct option is B Surfactants
Water is the most commonly used agent for cleaning around the world. But, it is not always effective for cleaning. This is because of higher surface tension of water. Water does not get adhered to dirt particles because of its higher surface tension. To reduce this surface tension, we use surfactants so that water can wet surfaces better and become effective in cleaning. Soaps and detergents are surfactants.
