GMAT Critical Reasoning (CR) | Re: For-profit colleges serve far fewer students than either

Conclusion:- “for-profit colleges enroll a greater proportion of financially disadvantaged students than do non-profit colleges.”
Negating answer choice B:-
“For-profit colleges do not engage in fraudulent practices in helping their students obtain unneeded federal and state financial aid”.
As colleges are getting engaged in fraudulent practices to get financial aid this concludes that students are not financially disadvantaged contradicting the conclusion. Hence choice B is correct.
