Detailed explanation-1: -The role of the ascending colon is to absorb the remaining water and other key nutrients from the indigestible material, solidifying it to form stool. The descending colon stores feces that will eventually be emptied into the rectum.

Detailed explanation-2: -The colon helps to absorb a small volume of water from the lumen (400ml/day).

Detailed explanation-3: -The large intestine functions to absorb any excess water from the material it receives from the small intestine. This also involves the collection of electrolytes, which move with water. Thus, the large intestine works to preserve and absorb water and electrolytes that were not absorbed by previous digestive organs.
