Parallelism is the repetition of the same grammatical structure across a list, group of phrases, or group of sentences. In this answer, the parallel element is the repetition of "no way to" follow by a verb and direct object. This answer also address that idea that you can't take back words by saying that the words can't be undone, erased, or forgotten.

Option D begins with a parallel structure but it's not continued through to the last sentence.
