D is correct. There are no subject changes; the use of “you” is consistent throughout the sentence. It doesn’t change to “they,” for example, all of a sudden, like the other choices do.
I believe it's 'D' because the original sentence is in second person (i.e. "you" and "your") and it makes the most sense. To me. I'm sorry if this is wrong after all.
The word rupture would best replace the word, "breach," because it has a similar definition to it. Also, plugging in the other answer choices wouldn't make sense, since they would't fit into the sentence.
