Answer:
D. passed away, deceased
Step-by-step explanation:
"That Old Straw Sojourner" is written by David Matheme. If you happen to read all the lines, you will know what the excerpt above means.
"Fallen father" in line 23 refers to the boy's father who passed away. When his father died from lightning, he started wearing his father's hat. It was memorable for the boy for it reminded him of his father as his hero. He would often wear it to school. He was so proud of his father that he thought his job as a farmer was cool. He then followed in the same path.
So, this explains the answer.
