14. Sunspots, vortices ofgas associated with strong electromagnetic activity, are visible asdark spots on the surface of the Sun but have never been sighted on theSun's poles or equator.
(A) are visible as darkspots on the surface of the Sun but have never been sighted on
(B) are visible as darkspots that never have been sighted on the surface of the Sun
(C) appear on the surfaceof the Sun as dark spots although never sighted at
(D) appear as dark spotson the surface of the Sun, although never having been sighted at
(E) appear as dark spotson the Sun's surface, which have never been sighted on

此题的正确答案是A，想问一下C为什么错了呢？Although引导让步状语从句，如果主语和主句主语一致，且谓语是be动词，那么主语和谓语不是都可以省略吗？另外E选项，OG解释说：this phrasing makes the sentence somewhat awkward and unclear，这里的this phrasing指的是什么呢？

感觉although是不是歪曲了本来句子的意思啊？。。句子本来没有"尽管...但..."的意思吧？
我也想问问在这个情况下have never been sighted 和 are never sighted 的区别，还有这个情况下 on 和 at 是不是不能互换的？
楼下好心NN解答下，谢谢

although从句前面是不是需要有逗号？C选项没有逗号

而且C选项若理解为主谓省略，时态也不对了

有几个错点（我的理解）
1. although后面要引导一个完整的句子 never sighted at 错
2. 我觉得 although引导的从句有修饰dark spots 的嫌疑
3. 句子感觉，没有A好

B不对是显而易见的。C中Although引导从句， although never sighted at xxx缺乏谓语动词所以不对（注意sighted不对谓语动词）。D跟C一样的问题，having been sighted xxx是短语不是句子。E中which就近指代surface改变句意且逻辑不通

同问，已经看过OG官方解释，请问诸位是否可以认为：只要是GMAT里考到的Although，只跟从句，出现although doing/done 必错？如果是这样，那我就领会GMAC的出题精神了。
这个point很重要，因为这个点明确了，这一类遇到，都很快可以破解了，多谢！

although后面的unclear我是这么理解的他可以指dark spot从来没被看到过也可指sunspot从来没被看到过（不止dark spot这一种形式，各种形式）我也同意楼上说C少一个谓语动词

如果E选项的which指的是surface，那后面的应该是have吧单数还是不明白。。。
