I'd say that the statement from FDR's speeches that uses parallel structure is C. American ships have been sunk; American airplanes have been destroyed.
Both of these independent clauses use the passive form of the verb - in the first clause, the passive form of the verb <em>to sink </em>is used, and in the second, of the verb <em>to destroy.
