C
The food moves to the small intestine, where most digestion takes place.
D
None of the above
Explanation: 

Detailed explanation-1: -Chyme moves from the stomach to the small intestine. The small intestine is the organ where the digestion of protein, fats, and carbohydrates is completed. The small intestine is a long tube-like organ with a highly folded surface containing finger-like projections called the villi.

Detailed explanation-2: -The movement of chyme through the small intestine is called segmentation. This involves localized contraction of circular muscles which moves food back and forth to allow mixing with digestive enzymes and provide sufficient time for absorption of nutrients.

Detailed explanation-3: -Stomach: An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste.
