Celeste is writing an essay on how caffeinated drinks negatively affect the teen brain. Which source would provide Celeste with the most useful evidence?

Celeste needs evidence about the negative effects of caffeine on the teen brain. A study on how caffeine interferes with brain development directly addresses both the effect and the brain-related focus of her essay. Bone loss is a negative effect but is not about the brain, while the other studies focus on caffeine levels or possible benefits.
