Stuck between B and D

I diagramed correctly and made the proper inference, however, I do not see the difference between answer choices B and D. Many is diagramed as some so they seem to be the same to me. Thanks in advance

@Konner,

(B) is a proper inference because the argument tells us that many economists appeal to intrinsic value/ non economic justification. For logic purposes, many=some, hence we can infer that some economists appeal to non economic justification. The issue with (D) is that is says that many environmental provide ONLY a non economic justification, whereas the argument never tells us whether the economists do in fact provide ONLY non-economic justification and no other type. Hence, this is an unwarranted inference. Does this make sense?
