D. 25 students from each 9, 10, 11, and 12 are chosen at random to be included in the survey

Answer 1

c

Explanation:

The survey method that is most likely to give inaccurate results is the one that only surveys students who have perfect attendance. This is because students who have perfect attendance are more likely to be motivated and conscientious, and they may be different from other students in other ways.

The other survey methods are less likely to give inaccurate results because they randomly select students from the entire student body. This means that the survey results are more likely to be representative of all students.
