The answer is option C "Band preference for school dance Rap Rock Country Row totals Grades 9-10 40 30 55 125 Grades 11-12 60 25 35 120 Column totals 100 55 90 245"

You can see because this tablet has to correct information from the data you see in the question for example: Rap 40, Rock: 30, Country: 55 which has the same data in option C.

Hope this helps!
