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
OA is A
First question. Is the 'as' in the choice A correct? I think it should be replaced by"like", "Sunspots,......, are visible LIKE dark spots on the surface of the Sun...." or it should be followed by a "are", "Sunspots,......, are visible AS dark spots ARE on the surface of the Sun...." because "like" is used to compare a noun and "as" a clause. Is the OG wrong or I am wrong?
Moreover, what's wrong with E? Is it wrong because the "which clause" unambiguously refers to the "surface"?
