Yes — "Yes, an observational study would be best for this scenario because a treatment is not being applied to the sample."

Explanation: Cesar would simply observe which students eat breakfast and compare their first-period grades. He is not (and likely cannot ethically or practically) assign students to eat or skip breakfast, so an observational study is the appropriate design.
