The correct option is C Absorbtion
Digestion is a five step process and it starts with ingestion of food, followed by their digestion in the stomach and intestine. The nutrients are absorbed by the villi and circulated in the body through blood and lymph. These nutrients reach the cells and tissues and become their internal component which is referred to as assimilation. Food which cannot be broken down and remain undigested are sent out of the body.
