Explanation:

A representative sample should be unbiased and reflect the entire student - body population. Asking students who work at the restaurant may be biased as they may have a more positive view. Randomly choosing 10 students in every grade and randomly picking 30 students' photos from different pages of the yearbook are random sampling methods that are more likely to produce a representative sample as they don't target a specific non - representative subgroup.

Answer:

B. Shannon randomly chooses 10 students in every grade to ask.
C. Shannon randomly picks 30 students' photos from different pages of the yearbook. Then, she asks those students.
