Correct answer: D. Hemorrhoids
- A. Bulimia
- B. Ulcer
- C. Adipose tissue

Hemorrhoids are swollen or dilated tortuous veins in the anorectal region, often causing discomfort or bleeding. An ulcer is an open lesion rather than a mass of dilated veins, so students may choose ulcer because both can produce rectal bleeding.
