Solution

The correct option is A

i. Egestion or Defecation ii. Colon iii. Neural reflex iv. Anal sphincter


The process of egestion or defecation is modulated by long powerful waves of contractions of the colon. Once the rectum is filled to 25% of its capacity, a neural reflex stimulates the desire to defecate. In response to this, we voluntarily relax the external anal sphincter to allow feces to pass from the rectum into the anal canal and out through the anus
