A. Yes, an observational study would be best for this scenario because a treatment is not being applied to the sample.
This option is correct because Cesar is interested in observing the relationship between breakfast consumption and grades without manipulating any variables or assigning students to different treatment groups. An observational study allows him to gather data on students' breakfast habits and their corresponding grades to see if there is a correlation.
