Among the options listed, the risk factors that you can control are related to your personal behaviors and choices rather than genetic or demographic factors. Specifically, the option "Your friends have recently started smoking" may influence your choices, but ultimately, the decision to smoke or not is under your control.
The other factors, such as the family history of heart disease and the incidence of high blood pressure in your ethnic group, are not controllable risk factors as they relate to genetics and demographics.
If you're looking to make responsible health decisions, focusing on controllable factors such as diet, exercise, smoking cessation, and stress management would be beneficial.
