A. Kennedy uses parallel structure: "pay any price, bear any burden, meet any hardship."
I think it's this one because one, the paragraph does not use analogy, which is to compare two very similar things or sometimes two very different things, and so, I don't see any comparing, and two, I don't see the use of juxtaposition, which is when you compare and contrast two very different things, ususally side by side. And so, I don't see this either. Parallelism or parallel structure is when you have sentences that sound the same by comparing things, using the words "like" or "as" and so on.
