'had long appeared' -- longer applied
immune to -- correct usage.

I though the correct sentence should have started with has, but they have the wrong idiom usage, is my explanation correct:

A) has long appeared that it was [b]immune from [/b]
B) has long appeared to have been immune from
C) has long appeared as being immune to (Correct idiom, but uses being)
D) had long appeared immune to (Correct idiom)
E) had long appeared that it was immune to (Correct Idiom, to long, and unnecessary use of it)

IMO D is correct here, since it was previously assumed that Ozone is immune at that level. But later it has been known that CFC from industrial emissions can deplete Ozone at that level, so we are in the past of past hence use "had", also immune to is the correct idiom.
