• B. Digestion$\to$Absorption$\to$Assimilation$\to$Egestion
• C. Egestion​​​​​​​$\to$Absorption$\to$Assimilation$\to$Digestion
• D. Digestion$\to$Absorption$\to$Egestion​​​​​​​$\to$Assimilation

Answer 1

The correct option is B Digestion$\to$Absorption$\to$Assimilation$\to$Egestion

$\bullet$ Food is taken into the digestive system through the mouth by the process of ingestion.
$\bullet$ These food particles are further broken down into simpler forms by the process of digestion with the help of enzymes.
$\bullet$ Once digested, vital nutrients are absorbed by the body by the process of absorption.
$\bullet$ Digested nutrients are then utilised for various purposes. This process is called assimilation.
$\bullet$ Finally the undigested portions are eliminated from the body by the process of egestion.
