Answer 1

The correct option is A Ingestion $\to$ Digestion $\to$ Absorption $\to$ Assimilation $\to$ Egestion

Food is first taken in from the mouth that is ingested. The food is converted to simple form i.e digestion and then it is absorbed by blood i.e absorption. The nutrients in the blood are taken to the cell for metabolic action i.e assimilation and then undigested food is thrown out of the body through anus that is egestion.

Thus, the correct answer is option A.
