A cross-sectional design would be best to determine which age group (10-year-olds, 12-year-olds, or 14-year-olds) is most likely to respond to the new advertising approach for Fruit Loops cereal. This design involves collecting data on different age groups at the same time, allowing for a direct comparison of their responses to the advertising approach. The other options (sequential, longitudinal, and pretest-posttest experimental) would not be as useful for this specific research question.
