Go for D." Immune to" is the correct idiom. Left with C,D and E. The correct tense is past perfect. Eliminate C. E is redundant. So D is the correct answer.
Note: If you are "immune to" something, it doesn't bother you.
If you are "immune from" something, it cannot be applied to you.

I don't know about the idiom part. my approach was based on meaning:
the verb tense is wrong. we need one type of past tense; so A, B, and C out.
between D and E: E is wordy (when the subject of the two sentence is the same, it is wordy to say"it had long appeared that it was immune to " just it had long appeared immune to" is enough)
So D wins.
