大家帮我看看这道题题干讲的是什么东东？

答案选对但题没看懂, 请高手指教一下，谢谢！

大全No.792：

The odds are about 4 to 1 against surviving a takeover offer, and many business consultants therefore advise that a company’s first line of defense in eluding offers like these be to even refuse to take calls from likely corporate raiders.  （B）

(A) that a company’s first line of defense in eluding offers like these be to even refuse
(B) that a company’s first line of defense in eluding such offers be to refuse even
(C) a company defending itself against offers of this kind that, as a first line of defense, they should even refuse
(D) companies which are defending themselves against such an offer that, as a first line of defense, they should even refuse
(E) that the first line of defense for a company who is eluding offers like these is the refusal even

Thanks to the "against", this sentence becomes elusive. But a conversion would make it easier to catch this sentence: odds 4 to 1 against surviving, so the odds of surviving is 1 to 4.

谢谢，语法到不成问题
