Solution

The correct option is C

Elephant's Toothpaste Experiment.
Concentrated hydrogen peroxide is first mixed with liquid soap. Then a catalyst, often potassium iodide is added to make the hydrogen peroxide decompose very quickly. Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creates bubbles, and turns into foam. This reaction is called Elephant's toothpaste experiment.
