Which part of this excerpt most clearly reveals that the narrator has monstrous qualities

d. I was rude and took pleasure in being so.

Explanation:

Fyodor Dostoyevsky's "Notes from the Underground" is a work that was first published in Russian. This novella is part of an introduction to the future novels by the writer while also a response or criticism of the novel "What Is To Be Done?" by Nikolay Chernyshevsky.

In the given passage, the narrator/ speaker reveals how he used to be. He declares that "[he] was rude and took pleasure in being so". Moreover, he also mentioned that "[he] was a spiteful official" which are all suggestive of his bad behavior. But most importantly, the part of the excerpt that reveals his monstrous quality is when he admits "[he] was rude and took pleasure in being so." This shows his ungrateful and unrepentant nature, more like he's proudly declaring it.

Thus, the correct answer is option d.  

- "the die is cast; i have consented to return if we are not destroyed. thus are my hopes blasted by cowardice and indecision; i come back ignorant and disappointed. it requires more philosophy than i possess to bear this injustice with patience. i have lost my hopes of utility and glory; i have lost my friend."
