The superintendent of a large school district is curious about the relationship between students' grades and their participation in extracurricular activities. They take a random sample of 500 students and find that students with more participation in extracurricular activities are far more likely to have high grades than students with little or no participation.

What conclusion can they draw from this study?

(Choice A)
For any two students in this study, the one who participated more in extracurriculars had higher grades.
(Choice B)
Any student in this study who participated in extracurriculars had high grades.
(Choice C)
There was an association between extracurricular participation and grades, but it's not necessarily a causal relationship.
(Choice D)
Extracurricular participation caused the students to have higher grades.
(Choice E)
