SC大全243求指点

1.?**Developing nations in various parts of the world have amassed $700 billion in debts; at stake, should a significant number of these debts be repudiated, is the solvency of some of the world’s largest multinational banks.
(A) should a significant number of these debts be repudiated, is

(B) should a significant number of these debts be repudiated, are

(C) should they repudiate a significant number of these debts, are

(D) if there is a repudiation of a significant number of these debts, would be（A）

(E) if a significant number of these debts will be repudiated, is

答案是A, 想确认一下E的问题，是因为at stake is the solvency...已经是倒装结构，所以if条件句不适用？还是说if条件中的will时态是错误的？请大牛指教！多谢！

if引导的虚拟语气，未发生的事情用一般时，即改为
if a significant number of these debts is repudicated, would be

不晓得，我做这个题的步骤，是，先看到倒装，然后确定谓语是单数
A D E保留 BC排除
再看D IF xxxx 一定错，排除
E， will be 错，排除
选A

谢谢！
这样看来，应该是if从句的时态错了。
