What is the climax in Willa Cather's short story "Paul's Case"?

APaul reads about his theft in the newspaper.
BPaul takes the train to New York.
CPaul meets the boy from Yale.
DPaul jumps in front of the train.

Verified Answer :

My choice is d. Paul jumps in front of the train.  Prior to this, he buries the flowers that
have wilted due to the cold in the snow.
This signifies his intentions to end his life.  He is alienated and misunderstood and this
summarizes his attitude towards life.
