The sample in this study is the college students who responded to the National Survey on Drug Use and Health. This is because the survey selected a random sample of U.S. college students and asked them about their illicit drug use, so the sample is limited to those who actually responded to the survey. Option A is too broad, as the survey only includes a subset of U.S. college students, and Option B only includes those who reported using illicit drugs, which is not inclusive of the entire sample. Option D is also incorrect, as the survey only focuses on college students and not all U.S. adults.
