Answer: C) Isolation.
Explanation: In literature, mood is a literary element that evokes certain feelings or vibes in readers through words and descriptions. We can also say that the mood is the emotional setting of the piece or its atmosphere. In the given excerpt from James Joyce's "Araby" we can see that the description of the house at the end of the block creates a mood of isolation, because it is uninhabited and it stood at the blind end.
