The correct option is C II $\to$ I $\to$ III

The large intestine basically has 3 jobs:
$\bullet$ Absorbs ions and nutrients: The main function of the large intestine is to absorb ions and nutrients back to the body.
$\bullet$ Absorbs water: A healthy colon absorbs 80% of the water that passes through it.
$\bullet$ Defecation: When water is absorbed, the fecal matter becomes dry. It is then ejected out through anus by reflex action. This process is called defecation.
