Final Answer :
A
Explanation :
A cross-sectional design compares different groups of individuals at the same time point. In this study, Dr. Ilka compared the math scores of students in different grades (fifth, third, and first) at the same time point. Therefore, the study utilized a cross-sectional design. The other options (longitudinal, time-lag, and correlational) would not be appropriate for this type of study.
