Answer:
The correct answer is D: Grim.
Explanation:
Although the speaker in this excerpt does seem to be reflecting on the situation, and his actions, and which is established by the constant use of the first person, the correct answer here is D, because of the vocabulary used in several places, and which establishes the dark mood that is overtaking the speaker. Words like "suspicion", and "darker" one, are clue words that allow the reader to understand the mood of the speaker and how he must be defined. He is a person who is led by not very cheerful thoughts, or actions either.
