C Correct answer
Explanation

This is the correct order. The food is first ingested through the mouth. It is then digested by breaking down in mouth cavity, stomach and small intestines. Then, the food is absorbed mainly by the small intestines. The absorbed food is then incorporated into the cell components in the process of assimilation. Lastly, the undigested food is excreted out in the process of egestion.
