Answer:
The answer is D) humor.
Explanation:
Mood can be defined as the atmosphere an author creates that involves readers. Usually, word choice and description of the setting, as well as imagery, help produce a certain mood. Readers present an emotional response to the atmosphere - happiness, tranquility, fear etc.
In the excerpt we are analyzing here, the words and phrases employed by the author create a mysterious aura, leaving readers hanging halfway between fear and thrill. There's an unknown man in a dark place. There is a policeman involved. Could he be a criminal? What are they talking about?
The only mood that is not supported by the passage is humor. There is nothing humorous about it, nothing that would cause a reader to laugh.
