Complete answer:
Peristaltic movements are the movements that the large tubes inside the body tends to make automatically to push something out. It creates a peristalsis phenomenon that brings about the movement of food and liquid. The peristaltic movement in the large intestine is the same as the small intestine. General contraction causes mass movements to take place one to three times a day to propel the chyme which is now towards the rectum. Rectum is the final straight portion of the large intestine. It is temporary storage for faeces. Lies in the front of the sacrum, and vagina and uterus in females. It is the concluding part of the large intestine which terminates in Anus. It simulates the urge of defecate. Comparing with the other parts rectum has the least peristaltic movements.

Thus, the correct answer is option C. i.e., Rectum.

Peristalsis movements In digestive system contains Esophageal peristalsis, Stomach peristalsis.
