A. "The child's diet" is a factor that influences the early detection of a childhood disease by a physician. An unhealthy diet will probably cause problems in health, which for a child who does have a healthy diet will not need to suffer. B. can affect a child mentally, but it won't cause a childhood disease. And C. and D. are just silly. A child will not get a disease based on how close the doctor's office is or if the kid is in school or not. Hope this helped!
