Well, the correct answer is A. I just checked the Official Guide (11th Edition).

Now, I feel better as I cannot understand what is wrong with A.
Thanks all. The mistake is originated from SC1000 (#677)

Can someone help me out here, I know this isn't even an answer choice...but why is it "sighted on" and NOT "seen on"?

"Sighted on" seems very awkward to me since I think of "sighted" as an adjective.

sight·ed
(of a person) Having the ability to see; not blind: "a sighted guide is needed"; "the blind leading the sighted, I thought".
Having a specified kind of sight: "the keen-sighted watcher may catch a glimpse".
