Answer
Correct answer: b) Both A & R are correct but R is not reason for A
Both statements are correct, but R is not the reason for A. Prophylactic (total) colectomy is indeed recommended for all patients with FAP, given the near-100% lifetime risk of colorectal cancer if left untreated (A is true). Classic FAP is defined by the presence of a minimum of 100 colorectal adenomatous polyps (R is also true). However, the reason prophylactic colectomy is performed is the overwhelming cancer risk from having numerous adenomas, not the diagnostic polyp-count threshold itself — the two statements are independently true facts, not cause-and-effect.
