Explanation

Looking at the bottom graph you can see the %. Actually, the question is asking you for the ratio public/private

Public 4 years + public 2 years = 41% + 37% = 78%

Private 4 years + private 2 years = 21% + 1% = 22%

$$\frac{78 %}{22%}= 3.5 %$$

D is the answer. Hope is clear now

Well, but if we use the top graph the result will be different.

Total enrollment public = Public 4 year + Public 2 year = 115+110 = 225
Total enrollment private = private 4 year + Puprivate 2 year = 115+90 = 205

Public / Private = 225/205 = 1.097 or 109.7% ...

We need to take into account the percentage (the second graph) not the total enrollment.

Hope this helps.

Thank you for your neat explanation. How i should know which figure i should use? I am not sure why we did not consider the first?

This is the tricky part.

You should infer from the stem. Moreover, this GRE (or GMAT) is all about: a test of reasoning.

From the bold part you might infer that you need the %. As such, the second graph.

Shouldn't you get the same answer if you use the first graph or the second? Shouldn't both of them give you the "approximately how many times" ratio they are looking for? What am I missing here?
