The correct answer is C, hypocrisy. This work of Mark Twain's is actually a fictionalized version of his own wartime experiences. He is trying to tell us that there is nothing glorious about war, that there is only death and suffering. It cannot be glorious when you have to kill somebody, or somebody will kill you. That's the irony and hypocrisy that Twain was trying to convey in this work.
That words would be
"Dummy" or "fraud" or "cheat"
The correct answer is The new cloak
I wanna say all of the above, because they could all be "fine art".
