The correct answer is B. Weight
Step-by-step explanation:
A non-communicable disease is one that cannot be transmitted, and due to this, these are the result of genetics and lifestyle or environmental factors. Examples of these diseases include cancer, diabetes, heart diseases or Parkison disease. Moreover, the probability of developing these diseases is related to different risk factors; this includes controllable factors such as weight, diet or drinking habits, and uncontrollable factors such as gender, ethnicity or heredity.
According to this, the only factor that can be classified as a controllable risk factor is weight because, through diet, exercise, and habits individuals can keep a healthy weight, and this reduces the development of non-communicable diseases such as diabetes or heart diseases. Also, other factors such as age, gender or ethnicity cannot be controlled or modified.
