The story line that is most likely the plot of a historical fiction novel is “ A young slave girl and her brother try to escape to freedom in the North, using the Underground Railroad.”
Explanation: Historical fiction is a genre of literature that takes place in the past. This answer mentions slavery, and the Underground Railroad, both which took place in the mid-19th century when enslaved African-Americans used the Underground Railroad network to escape into free northern states or Canada. Since these events are apart of history, this answer would most likely be the plot of a historical fiction novel.
The other answers explain events that could take place in the present.
