Unlike
George Wallace in 1968 and John Anderson in 1980, both of whom running as independent candidates, H. Ross Perot's independent run for the presidency in 1992 arose not from an unsuccessful effort to gain a major party nomination but from a desire to establish a viable third party in American politics.
A. George Wallace in 1968 and John Anderson in 1980, both of whom running as independent candidates,
B. George Wallace in 1968 and John Anderson in 1980, each of whom ran as independent candidates,
C. George Wallace in 1968 and John Anderson in 1980, both of which ran as an independent candidate,
D. the independent candidates, George Wallace in 1968 and John Anderson in 1980,
E. the independent candidacies of George Wallace in 1968 and John Anderson in 1980,
答案E
知道unlike需要结构对称，但想不通E和后面是怎么对称法的。。。难道是要大结构对称不能用从句？
如果Ａ，Ｂ，Ｃ中出现从句，主谓一致用法正确的选项，比如George Wallace in 1968 and John Anderson in 1980, each of whom ran as an independent candidate可以选吗？

先不管主谓一致的情况，A B Ｃ D unlike之后是两个候选人，而主句的主语是名词结构 ’H. Ross Perot's independent run for the presidency‘，其中run(竞选)是中心词。
举个例子：
unlike Jack, I like coffee very much
unlike 引出平行结构，一方是Jack, 一方是 I， Jack 和 ‘我’ 平行对应。
但是 A B C D 选项中，与主语 ‘ run’ 对应的是两个人，不构成平行。
如作出改动，需要将主句的主语 'run' 变成 ‘ross, Perot' 这个人。
排除 A B C D
E 选项中unlike 后面的名词结构时 ’candidacy‘ （竞选人资格）可以和主句中的 主语结构中心词 ’run‘ 对应。
下面是我google的一些candidacy的例句，其含义好比中文译词’竞选人资格‘要广，可以涵盖竞选的意思
If his improbable candidacy started out as an attempt to drum up publicity for his suddenly best-selling autobiography, however, it is no longer a laughing matter.
Boneham said in a speech announcing his candidacy. “If the government puts up roadblocks, then they should be repealed.”
所以，您改动的选项也不能选，因为无法和 'run' 对应

这回egoislwlv伙计说得有理了
补充一点：就像很多词的错误翻译一样，中文（至少在绝大多词典）翻译candidacy为“xxxx资格”本身就是错的。这个词没有qualifications的含义。
