two high school sweethearts go their separate ways after
a misunderstanding. years later, both are happily married
to other people and discover that their children are in the
same kindergarten class.
which plot development would most logically lead
a reader to conclude that the themes of this story
are forgiving oneself and others and embracing
new beginnings?

In this example, the couple parted ways in the past because of a misunderstanding. This would make it reasonable to believe that the two are angry or resentful at each other.

If the themes of the story are about forgiving oneself and others and embracing new beginnings, then it would be likely that the couple would decide that they do not want to be angry at each other anymore. Instead, the couple would most likely decide to forgive each other and start fresh again, as friends. This is the plot development that would most logically support such a theme.
