The correct answer is C.
The image of fellow citizens rising up and drowning the enemy in a wave of "pride and knives" demonstrates that they will remain defiant. It also best develops the speaker's viewpoint that adversity only makes his compatriots stronger.
the correct answer that best describes the excerpt of that story is:
"You pretended envoy extraordinary and an agent to and from Jupiter Tonans," laughed I; "you mere man who come here to put you and your pipestem between clay and sky, do you think that because you can strike a bit of green light from the Leyden jar, that you can thoroughly avert the supernal bolt? Your rod rusts, or breaks, and where are you? Who has empowered you, you Tetzel, to peddle round your indulgences from divine ordinations? The hairs of our heads are numbered, and the days of our lives. In thunder as in sunshine, I stand at ease. False negotiator, away! See, the scroll of the storm is rolled back; the house is unharmed; and in the blue heavens I read in the rainbow, and will not make war on man's earth"
