Answer:
C: more personal is the correct answer.
Explanation:
Since the speaker (the father of the son who is introduced) wants to share some personal information, like the background of the kid and how he was raised, the tone is personal. It is also important to point out that the text opens with the phrase Dear teacher, showing that the speaker wants to create and intimate, personal bond between him and the teacher.
