Some buildings that were destroyed and heavily damaged in the earthquake last year were constructed in violation of the city's building code.
A)Some buildings that were destroyed and heavily damaged in the earthquake last year were"destroyed and heavily damaged" is nonsensical. A thing cannot be destroyed and damaged at the same time.
B)Some buildings that were destroyed or heavily damaged in the earthquake last year had been"Last year" modifies "earthquake". "Had been constructed" indicates the point in time before "were destroyed". Makes sense.
C)Some buildings that were destroyed and heavily damaged in the earthquake last year have beenWrong for the same reason as A.
D)Last year the earthquake destroyed or heavly damaged some buildings that have been"Have been constructed" means that the buildings still stand illogically neglecting the earthquake.
E) Last year some of the buildings that were destroyed or heavily damaged in the earth quake had been."that were destroyed..." is a modifier of "the buildings", making "Last year" a modifier of "had been constructed".
I do not understand why option D is incorrect? Because if you see, if the buildings got constructed after the earthquake then they must be standing still in the present. And hence, use of have should be CORRECT.
