Which of the following occurs during the climax of the story?

A. The protagonist kills the old man.
B. The protagonist confesses because he hears the old man’s heart beating again.
C. The protagonist admits he is insane to the police officers.
D. The police arrest the protagonist, and he is committed to a mental institution.

D. The police arrest the protagonist, and he is committed to a mental institution.

The correct answer is D. The police arrest the protagonist, and he is committed to a mental institution.

To determine which of the options occurs during the climax of the story, we first need to understand what the climax is. The climax is the most intense and pivotal moment in a story, where the tension and conflict reach their peak.

To find the answer, we need to analyze each option:

A. The protagonist kills the old man - Killing the old man seems to be a significant event, but it does not necessarily indicate the climax.

B. The protagonist confesses because he hears the old man’s heart beating again - Confessing due to hearing the old man's heart beating again could be seen as a climactic moment, as it suggests an intense emotional realization on the part of the protagonist.

C. The protagonist admits he is insane to the police officers - This choice could be seen as a crucial revelation. However, whether it constitutes the climax depends on the context and significance of the admission within the story.

D. The police arrest the protagonist, and he is committed to a mental institution - The arrest and commitment of the protagonist could be seen as a consequence of the events leading up to the climax, but it may not represent the climax itself.

Based on these considerations, option B, where the protagonist confesses because he hears the old man's heart beating again, seems to align most closely with what might occur during the climax of the story.
