A Correct answer
Explanation

This is the correct order of food flow in the alimentary canal. The masticated food from mouth reaches oesophagus from where it is pushed into the stomach. In stomach, the food is churned and converted into semi-solid paste which is then pushed into small intestines. In small intestines, the food is digested and absorbed. The undigested food is further passed into large intestines, where water is absorbed from the undigested food. The undigested waste is passed into rectum, where it is stored in semi-solid faeces.
