Mr. John tracked the number of hours spent reading by students in two different classes over summer break. Each dot represents a student.

Which statement correctly compares the data?

A.
Class A students generally spent the exact same number of hours reading as class B students.
B.
Class B students generally spent more hours reading than class A students.
C.
Class A students generally spent more hours reading than class B students.
D.
Although the mean number of hours spent reading by class A students is generally greater than the mean number of hours spent reading by class B students, the variability creates too much overlap for any conclusion to be made.
