Answer:
A. detached and impersonal
Step-by-step explanation:
The form of narration of the 1st section of Ambrose Bierce's "An Occurrence at Owl Creek Bridge" is detached and impersonal. The narrator seems to be a third person omniscient narrator, describing the hanging from a distance while giving the surrounding and characterization of the man to be hanged. The way of narration doesn't have any feeling of compassion or sympathy for the protagonist, nor does it attach any emotion to the man who was to be hanged.
