请问大全的SECTION 2中的第五题

5.     The city’s public transportation system should be removed from the jurisdiction of the municipal government, which finds it politically impossible either to raise fares or to institute cost-saving reductions in service. If public transportation were handled by a private firm, profits would be vigorously pursued, thereby eliminating the necessity for covering operating costs with government funds.

The statements above best support the conclusion that

(A) the private firms that would handle public transportation would have experience in the transportation industry

(B) political considerations would not prevent private firms from ensuring that revenues cover operating costs

(C) private firms would receive government funding if it were needed to cover operating costs

(D) the public would approve the cost-cutting actions taken by the private firm（B）

(E) the municipal government would not be resigned to accumulating merely enough income to cover costs

请问为什么不可以选C阿？B我反倒看不出来！

不对吧？

这应该是一道归纳题，并不是问assumption阿？
