Detailed explanation-1: -Large intestine is the last part of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as faeces before being removed by egestion or defecation.

Detailed explanation-2: -By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished. The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.

Detailed explanation-3: -Absorption of ingested water and most solutes occurs in the proximal small intestine, therefore the rate at which beverages are emptied from the stomach is an important factor in determining the rate of water absorption.

Detailed explanation-4: -Large intestine absorbs vitamin B12, water and some salts from the undigested food.
