Critical Reasoning

I dont agree with the explaination provided because as I see it B is the inverse of what is said in the prompt

because the representation of the social scientist is limited than less funding for social science
because X than Y

now B states that
if reprsenation is increased than the funding would ibccrease
which isthe same as saying
if not (less representation) than not(less funding)

GMATGURUNY could you please explain where I am wrong in my understanding
