Nitrogen Between Two Diamonds

[G]

This is a crazy Question I got on GmatPREP 1

By Pressing a tiny amount of Nitrogen between two diamonds to a pressure of 25 million pounds per square inch, scientists not only were able to transform the gas into a solid, but they also created a semi-conductor similar to Silicon

A) Same
B) not only were able to transform the gas into a solid but also creating
C) were able not only to transform the gas into a solid but to create
D) were able not only to transofrm the gas into a solid but also creating
E) were not only able to transform the gas into a solid, but they were also able to create

Is any of the answers right ???

On second thoughts I would say C to maintain parallelism. None of the other sentences are parallel... Ron, can you confirm the ans for this. Thanks
