The correct answer is B. Yes. Students in the music class will probably enjoy listening to music more than other students.
This option indicates a potential bias since the group surveyed (students in the music class) may have a predisposition towards enjoying music, which could influence their preference for doing homework with background music compared to a broader sample of seventh graders.
