Question:

Which of the following conclusions is supported by the data in the graph above?

A Biology is the most popular science class(C)

Explaination

Mathematically, choice (A) and (B) are incorrect. Answer choice (D) might be true, but the chart does not distinguish between important and unimportant classes, so this choice is a matter of unsubstantiated opinion. Biology has a higher percentage of enrollees than the other science classes, so answer choice (C) is correct.
