The box plot compares the number of events that Mrs. Cai’s and Mr. Roland’s classes won over the last 10 years on the school’s field day.Based on the data in the box plots, what is the best evidence to show which class has had greater success on field day over the last 10 years?

Question illustration
A
Mrs. Cai’s class was more successful because her interquartile range was less spread out.
B
Mrs. Cai’s class was more successful because she had the greater total spread.
C
Mr. Roland’s class was more successful because his class always won at least one event.
D
Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
