although引导的状从能不能省略主语啊

Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on
the surface of the Sun but have never been sighted on the Sun’s poles or equator.

(A) are visible as dark spots on the surface of the Sun but have never been sighted on
(B) are visible as dark spots that never have been sighted on the surface of the Sun
(C) appear on the surface of the Sun as dark spots although never sighted at
(D) appear as dark spots on the surface of the Sun, although never having been sighted at
(E) appear as dark spots on the Sun’s surface, which have never been sighted on

不讨论这个题怎么做，我局想问问C中我看OG解释说although typically introduces a subordinate clause, which has a subject and a verb,
but here there is no subject,那么问题来了，although 引导的状语从句是都得有完整的主谓吗，还是说有时可以省略，比如主语相同时
，如果省略的话谓语呢也省吗，求教

状语从句可以省略的前提有两个：1，从句的主语和主句的主语是同一个（或者是it），2 从句的谓语动词必须是be动词
这道题我试着解释一下C选项
appear on the surface of the Sun as dark spots although never sighted at
那么这个句子如果是符合省略要求的话，还原回来应该是 Sunspots appear on the surface of the Sun as dark spots although [Sunspots are] never sighted at....
但是在这里涉及到了一个主从句时态的问题，这里原题想要表达的是have never been sighted, 如果想要表达这层意思的话就必须把have been 写出来，省略原则之所以可以省略be，是因为be一般都不是什么重要的因素（一般时态和主句的时态一致，这点是我自己看题理解的），而这里显然不是这种情况。
这里如果要把have been写出来，那么就必须也补全主语，省略的话是主语谓语动词同进同出的，不会出现只省略主语或者只省略谓语动词的情况。这里sighted是过去分词。
举例说的话，although (he was) tired, he kept on studying. 这里的主语和从句主语一致，也是系动词，所以可以省略。
