=== Assistant: Excellent — ✅ お父さんは医者です。 ===
Excellent — ✅ お父さんは医者です。

Perfect grammar and kanji use again.
Small cultural note for flavor:

: 

Using お父さん implies you’re speaking to him (“Dad, you’re a doctor”) or referring to someone else’s father politely.

So:
* Talking to him → お父さん
* Talking about your own father → 父（ちち）
* Talking about someone else’s father → お父さん

You’ve now finished Part I (A–C) completely and perfectly.
Every answer was correct — the few refinements were cultural or stylistic.

Would you like to move directly to Part II (questions & answers) now,
or call it a night and continue tomorrow?
