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

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.

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.

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.

Cancer is primarily caused by insufficient dietary fiber; therefore, only fiber supplementation is necessary to prevent all cancer types regardless of other exposures.
