The biography of the James family, which included Henry, the literary master, and William, the famed psychologist-philosopher, showed that this extraordinary family was not immune to the kind of Victorian-era dysfunction that contributed to the insanity and early death of Henry and William's sister Alice.

1) that this extraordinary family was not immune to the kind of Victorian-era dysfunction that contributed


2) that this extraordinary family had no immunity to the kind of Victorian-era dysfunction contributing


3) this extraordinary family not to be immune from the kind of Victorian-era dysfunction that was a contribution


4) this extraordinary family as having no immunity from the kind of Victorian-era dysfunction contributing


5) this extraordinary family was not immune to the kind of Victorian-era dysfunction, and it contributed

Answer: A


In option A we have "showed" in the simple past tense, so does it make sense to have a past perfect after that for the sentence "extraordinary family had no immunity to the kind" rather than having simple past again " extraordinary family was not immune to the kind"?
