Answer
# Brief Explanations:
Selection bias occurs when certain members of a population are systematically excluded from the sample. Here, right - handed students are excluded from the sample of all college freshmen, which is a form of selection bias. Non - response bias is related to individuals not responding to a survey. Non - selection bias is not a standard term in this context. Response bias is about how respondents answer questions, not about who is included or excluded from the sample.
# Answer:
D. Selection bias
