I'm pretty sure the answer you are looking for is C rhetorical question though I'm not sure. I've looked the question up on quizlet though it didn't come out well idk it wasn't very understandable, though I am pretty sure it is C. Hope this helps.
I would say that "constant cry" and "Chesterton's cat" are the obvious ones. However "echoed in our ears" is a pretty subtle one that you can definitely make a solid argument for.
