B Correct answer
Explanation

The conclusion that the author draws is that sixty percent students reside in their home districts year-round will be most seriously weakened if students keep changing their residential status frequently. That way the result of the studies would hold but the conclusion drawn by the author would not. Hence, option (2) is correct.
