The correct response is: Yes, an observational study would be best for this scenario because a treatment is not being applied to the sample.
In this case, Cesar is interested in comparing the grades of students who eat breakfast versus those who do not, which can be effectively studied through observation rather than experimentation. An observational study allows researchers to examine relationships between variables without manipulating them, making it suitable for this situation.
