In C and D, sighted AT the Sun's poles does not convey the intended meaning: it implies that sunspots have never been sighted by anyone located AT the Sun's poles. The intended meaning of the SC is that sunspots have never been sighted ON the Sun's poles. Eliminate C and D.

In B, dark spots that never have been sighted on the surface of the Sun changes the meaning. The intended meaning is that SUNSPOTS (not dark spots) have never been sighted on THE SUN'S POLE OR EQUATOR (not the surface of the sun). Eliminate B.

In E, which have refers to dark spots, implying that dark spots have never been sighted on the Sun's poles or equator. The intended meaning of the SC is that SUNSPOTS have never been sighted on the Sun's poles or equator. Eliminate E.

The correct answer is A.

Hi GmatGuruNY , I apologize for referring to the wrong example
I have read that the that modifier could refer to x
in the
X + preposition + Y + that structure
could we say the same of
X + preposition + Y + which structure

Take for example the following sentence
i walked on the road to aden,which is famous for its tigers .
I understand that this sentence has been badly written but you must have got an idea of what exactly i am asking .

The correct answer is A.
In Choice E, do you mean the sentence structure is right and the function of which is right, but it changes the sentence meaning?
E conveys a meaning that is not only different from the original but also ILLOGICAL on its own.
E: Sunspots appear as dark spots on the Sun's surface, which have never been sighted at the Sun's pole or equator.
Here, which have (which + plural verb) seems to refer to dark spots (the nearest preceding plural noun).
While the portion in red conveys that sunspots appear as dark spots on the Sun's surface, the portion in blue conveys a CONTRASTING MEANING: that dark spots HAVE NEVER BEEN SIGHTED at the Sun's pole or equator.
COMMA + which cannot serve to introduce a contrasting meaning.
To indicate contrast, a connnecting word such as although or but is needed.
Eliminate E.
