Type II error is called false negative, that mean that you say the null hypothesis is right when it is not. In this case, the null hypothesis is "the drug is not safe". Then the error should be <span>to conclude the drug is safe when in, fact, it is unsafe</span>.

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!
