Answer:
A. Dissatisfied
Step-by-step explanation:
In the beginning of the excerpt, there are many uses of simple and concise sentence structures and a sense of discontent, such as "That was all".
Also, O. Henry includes harsh connotative word choice to effectively describe the apparent disatisfaction of the speaker, exaggerating the situation of how difficult it was to scrape up enough money, using words like "bulldozing" and "silent imputation of parimony". Using such words builds emphasis and importance of what lengths the speaker must endure in order to collect money.
When describing the "furnished flat", it's described as that "it did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad". Depicting the flat in such a way evokes a disappointed tone towards how the speaker feels about the flat.
