In Daisy Miller, Henry James uses third person narration.
I believe the correct answer is pleasant and attentive.
The author is stating in the excerpt that he though he would be getting his freedom back because of his 'gentleness and good behavior.' He wanted everyone around him to feel happy but also to do good things in order to be free again.
A first-person narrator.
An unreliable narrator is a narrator you can't trust
And third person, both limited and omniscient would use he and she.
