Answer

Brief Explanations:

A random sample should be representative of the entire population and not biased. Option A only samples math - class students, which may not represent all students. Option B only samples students at bike racks, likely over - representing those who bike to school. Option D is just one person and not a sample. Option C polls students in the cafeteria, which is more likely to include a diverse cross - section of the student population.
