The options to choose from are:
A. her sexual partners and her age
B. her age and heredity
C. heredity and her sexual behavior
D. her sexual behavior and smoking
The correct answer is D.
Her sexual behavior and smoking are controllable risk factors for this woman in terms of female reproductive cancers. She doesn't have any control over her age, her heredity or the amount of sexual partners she has had in the past. What she can do now is reduce the risk of developing cancers from being more sensible when it comes to sex and always making sure she is being safe and reduce and quit her smoking.
