The correct answer is: B. in
The preposition “in” is used to indicate a location or position. In this case, the speaker is saying that their first lesson in forgiveness came from their father. This means that the lesson took place in the context of their relationship with their father.
The other options are incorrect because they do not make sense in the context of the sentence. The preposition “on” is used to indicate a surface or area. The preposition “about” is used to indicate a topic or subject. The preposition “upon” is used to indicate a cause or reason.
