What is a chemical phenomenon in which an organic molecule splits into simpler substances?

Excretion
Fallout
Fermentation
Fatty acid

The correct answer is: Fermentation

This is a question about organic chemistry and the process in which organic molecules break down into simpler substances. The choices A, B, and D are all unrelated to this chemical phenomenon. Excretion is the process of removing waste from the body, fallout refers to the descent of radioactive particles from the atmosphere, and fatty acids are building blocks of lipids, not necessarily a product of this specific chemical process. Therefore, the correct answer is C, fermentation, which is a common example of this type of chemical reaction. Fermentation is the metabolic process in which an organic molecule, often a sugar or carbohydrate, is broken down into simpler substances, usually with the release of energy. This process is used in many industries, such as brewing and baking, and is also an important part of cellular respiration in organisms.
