Correct Answer: large intestine

Solution : The correct option is the large intestine.

The sigmoid colon is a section of the large intestine, also known as the colon. Between the descending colon and the rectum, it is placed. The sigmoid colon's primary role is to store and transport faecal material until it is removed from the body via the anus during the defecation process. The sigmoid colon is distinguished by its "S"-shaped curvature, and its role in the digestive system is critical for waste processing, and removal.
