whether x or y idiom

There was great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validated its historical importance along with its literary eminence hitherto

A. was great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validated

B. had been great debate among Greek historians whether the city of Troy ever existed or was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validated

C. was great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that had validated

D. had been great debate among Greek historians whether the city of Troy had ever existed or had been a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that has validated

E. had been great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validates


There are two actions here
1. great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction for some time
2. noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy,
a discovery that validated its historical importance along with its literary eminence hitherto

Great debate happened before and until the discovery.
so past perfect tense is needed here.

Given sentence uses simple past tense and therefore is an incorrect choice.
A, and C contain the same error.

Options also contain whether X or Y, where X and Y are parallel.
[list=]Whether the city of Troy ever existed or was a figment of fiction,
or
Whether the city of Troy ever existed or it was a figment of fiction[/list]

which of the above is the correct usage of whether x or y.
Plz explain regarding this idiom.

C. was great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that had validated
past perfect tense is used wrongly to depict that discovery is the earlier one of the two past events.

E. had been great debate among Greek historians whether the city of Troy ever existed or it was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validates
present tense verb validates gives a wrong meaning as the action took place in the past.

left with B and D.

B. had been great debate among Greek historians whether the city of Troy ever existed or was a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that validated .

D. had been great debate among Greek historians whether the city of Troy had ever existed or had been a figment of fiction, until the noted archaeologist Schliemann discovered in Turkey a site that many believe to be the ancient city of Troy, a discovery that has validated

I chose B over D.
Can you explain how can we use
    present perfect tense has validated for discovery and
    past perfect tense for whether x or y idiom.

this is a bad problem, and you should ignore it.

first, 'until X time' is a past time-stamp, and so should go with the normal past tense. (we write I was out of town until yesterday, not I had been out of town until yesterday.)

second, 'existed' should also be in the normal past tense, because it's a historical fact that is either true or false. (e.g., I don't think Albert Einstein ever wrote a book—not 'had written').

third, either 'validated' or 'has validated' would be perfectly fine in this context.

...so, yes, definitely ignore this problem, and be wary of problems from this source going forward.
