Final Answer : A, Explanation :  Haustral churning refers to the movement of the large intestine in which the haustra (pouches in the wall of the large intestine) contract and relax, mixing the contents of the intestine back and forth. This process aids in the absorption of water from the intestinal contents, as it allows for more surface area for the water to be absorbed from.
