Correct Answer � D
Explanation

Answer : D Stercoral ulcer
Incomplete evacuation of the feces, usually in association with debilitating disease or old age, may lead to the formation of a large mass of stool that cannot be passed, termed fecal impaction.
Stercoral ulcers result from pressure necrosis of the mucosa caused by the fecal mass. Complications include rectal bleeding and perforation. The other ulcers do not occur in the rectum.
