I have a question about the short story "Son" by John Updike.

Is "Son told in
a.order from the contemporary father and his memories and reflections
b.reverse chronological order, from past to present
c.fragments that are set in different time periods and all from contemporary son's point of view
d.segments, each told by a different character and all in the first person

I'm certain it is not "c" and I know it is the father starting out talking about his son and then reflects back
Any help would be greatly aprreciated. I have to pick the right answer and then right an essay to support it by tomorrow.
Thank you
