Which statement correctly characterizes cancer and dietary strategies to lower its risk?

• A. Cancer is an autoimmune reaction that targets healthy tissues, so avoiding fruits and vegetables, which can stimulate immune responses, is the most effective dietary preventative strategy.
• B. Cancer is uncontrolled cell growth from DNA mutations; reducing exposure to carcinogens like tobacco, alcohol, and processed meats and increasing fruits, vegetables, and whole grains lowers carcinogenic burden and supplies protective phytochemicals.
• C. Cancer refers to aging-related decline in all tissues; a diet high in red meat and processed foods has no relation to mutation rates or cancer incidence.
• D. Cancer is primarily caused by insufficient dietary fiber; therefore, only fiber supplementation is necessary to prevent all cancer types regardless of other exposures.
