Question: A school collects data on whether students participate in after-school sports and whether they complete their homework regularly. The results show: ""85% of students who play sports regularly complete homework"" and ""60% of students who don’t play sports complete homework"". The principal claims: “Playing sports helps students complete homework more often.” Which reasoning most accurately evaluates this claim?
A) The claim is correct because students who play sports always do better in school.
B) The claim is unsupported because correlation does not imply causation.
C) The claim is valid because 85% is more than 60%.
D) The claim is invalid because playing sports reduces study time.
