Correct Answer: B

Rationale: Colorectal cancer risk factors are well-documented, with family history being a major non-modifiable contributor due to genetic predisposition (e.g., Lynch syndrome). Physical inactivity increases risk by slowing bowel motility, allowing carcinogen exposure, but it's less definitive than genetics. A high-fiber diet reduces risk by promoting regular bowel movements, not increasing it, so it's incorrect here. Age over 50 is a strong risk factor as incidence rises with age, but family history often trumps it in teaching specificity due to its hereditary link. Emphasizing family history educates the client on screening needs (e.g., earlier colonoscopy), aligning with guidelines like those from the American Cancer Society. It's a critical, actionable factor, driving personalized prevention and surveillance, making it a standout choice for inclusion in teaching.
