A. The United States will be affected by whether Taiwan develops a closer relationship with mainland China or preserves the status quo

B. Whether or not Taiwan develops a closer relationship with mainland China or preserves the status quo affecting the United States
                

C. Whether or not Taiwan develops a closer relationship with mainland China or the status quo is preserved, it will affect the United States

D. It affects the United States whether Taiwan will develop a closer relationship with mainland China or preserves the status quo

E. It affects the United States whether or not Taiwan will develop a closer relationship with mainland China or preserve the status quo

答案选a,我选的d,但解释说D的whether ...or 不平行，是指时态不平行吗? A用被动不好啊。

请nn指教

明显Ｄ的时态不平行啊

在Ｄ不对的情况下，Ａ的被动也是最佳的

C: 两个句子并列没有联词

是指哪两个句子啊?

我觉的第一句是个条件状语，第二个是主句，第三句是原因状语，只有一个主句为什么要连词啊？
