Eliminate
(A) and
(C) because they do not have any reference to the
masterpieces.
Choice (B) introduces an unnecessary relative pronoun
which, so it can be eliminated.
Choice (D) correctly changes the tense of
were to
are and introduces those to refer back to the
masterpieces earlier in the sentence.

were to
had to be and introduces an incorrect prepositional phrase
in those earlier years, so
(E) can be eliminated. The correct answer is
(D).
