I am inclining towards C for the usage of sighted at . Can anyone explain which one is idiomatically correct? Sighted at vs Sighted on ?

The use of sighted on v. sighted at depends on context and is not idiomatic. If one were to say "she was sighted at the baseball game" or "he was sighted on the roof" then either construction would be correct.

Don't you think appear is more concise than are visible as . Also poles and equator are imaginary, so can you spot something on imaginary lines/poles? Should sighted at be used in such cases or sighted on?

I disagree, you can be 'sighted on' places.

He was sighted on the roof. NOT He was sighted at the roof.

The sunspost were sighted on the surface. NOT The sunspots we sighted at the surface.

I think it depends if you can physically be 'on' something.

I will go for D.
C has a problem, it says appear on the surface of the Sun as dark spots..I prefer
appear as dark spots on the surface of the Sun. Besided in this sentence never having been sighted is better than just never sighted.. Never sighted singals like never sighted untill now..

Agree.
May be something to do with the usage of 'although' and 'but'.

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 Suns surface, which have never been sighted on

I choose A.

Funny thing is that it just sounds correct, I don't feel like I have a logical explanation...

A. are visible as dark spots on the surface of the Sun but have never been sighted on [Hold it]

B. are visible as dark spots that never have been sighted on the surface of the Sun [ Awkward construction – eliminate it]

C. appear on the surface of the Sun as dark spots although never sighted at [“Although” creates subordinate clause – missing “Subject” – eliminate it]

D. appear as dark spots on the surface of the Sun, although never having been sighted at [“Although” creates subordinate clause – missing “Subject” – eliminate it]

E. appear as dark spots on the Suns surface, which have never been sighted on [“Which” incorrectly modifies Surface – eliminate it]

Terrific pickup Yana !!!!! the OA is indeed A.

I got it from SC1000 where the OA is C - hence I thought I got it wrong. But I was right all along. +1 for this Yana

Great discussion guys - find the OE in OG11 Q9 from sentence correction section.
