Which of the following is listed as an age risk factor?

• A. Premature infant
• B. Cancer with increased age
• C. Sunbathing
• D. Industrial exposure

Answer: (B)

Age increases cancer risk because mutations accumulate over time and the body's ability to repair DNA and fight abnormal cells can decline with aging. This makes cancer more likely as people get older, which is why the option describing cancer with increased age is the best answer. The other choices reflect factors related to birth status or exposures, not age itself: being a premature infant is about birth timing, while sunbathing and industrial exposure involve behaviors or environments that influence risk but are not the aging factor itself.
