Explanation:
The correct option is 1, which is (Chyme). The semisolid mixture of partially digested food, saliva, and digestive juices in the stomach is known as chyme.
This thick, semi-liquid mixture is created as food is broken down by stomach acids and enzymes, resulting in easier digestion and absorption as it moves into the small intestine.
Specifically, chyme is produced in the stomach, then moves to the small intestine, where it mixes with bile, which helps in emulsifying fats, and passes through the pyloric sphincter to enter the duodenum, which is the first part of the small intestine.
