The correct answer is C. It demonstrates Mr. White's unhappiness with his current lot in life.
Explanation:
In literature, the development of a character refers to the methods the author of a literary text uses to create a complex character with motivations, defined personality, and specific reactions to the events in the story. In the case of the paragraph presented from the story The Monkey's Paw, this focuses on the character of Mr. White. Also, the words of this character show his unhappiness with his life as he complains about the location of his house "That's the worst of living so far out," and in general he feels pretty unsatisfied. This means the paragraph demonstrates Mr. White's unhappiness (option C).
Moreover, this detail contributes to the development of the character because it shows the character's attitude and personality, and this affects the story (The Monkey's Paw) because due to his unhappiness Mr. White and his wife later use a magical object (a monkey's paw) to try to make their life better, which has terrible consequences.
