The focal point here is not the order of the words you point out, but rather where they occur in the sentence. B does not make sense because it says the spots are visible and have not been sighted. This is not possible because if they have not been sighted, there would be no way to know they are visible.

GMAC typically places an adverb BETWEEN the helping verb and the verb being helped. The following examples are all from OAs in the OG12:

are IN EFFECT told
it would IN THE PAST have conceded
have NEVER been sighted
can HARDLY be said
can CONSTANTLY change
have RECENTLY discovered
were EVENTUALLY exhibited
were FIRST aired
can QUICKLY analyze
would LATER make
are CLOSELY related
has ALREADY stimulated
is WIDELY accepted
