I know the following question has been answered in the forum but no discussion explains the query I have about E & A options. Please help.

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

请问：
C 可否理解为 although （it is ) never sighted at
E 在名词+介词短语，which 这样结构中，which指代名词吗？

昨天我也做到这里选了E来着…今天再读了一下选项。结合答案说下个人理解。
A有but表示转折和对比的意思：sunspots在太阳表面看得到，但是在赤道和两极不能看得到。
E是一个从句有修饰但是没有对比的意思，语意不如A表达的好。
等专业解释…

although我被你说服了，好像很有道理??

E which 修辞的名词有歧义可以是Sun's surface
