Answer:
c. By involving the narrator with an odd cast of characters.
Step-by-step explanation:
Washington Irving's collective book of "Tales of a Traveler" includes the section of "The Adventures of the Mysterious Picture". This story deals with the strange, somewhat horror story of a group of travelers staying in a mansion of one of their friends.
This group were then told by their host that there is a haunted chamber but it will be seen whose room was the next morning. They will have to wait to see who the hero of the night will be. This story is infused with elements or horror, with the narrator of the story unable to sleep peacefully in the chamber allotted to him. This excerpt given in the question exemplify Gothic fiction in involving an odd cast of characters with the narrator.
