Answer:
Definitely the first one, probably the second and third as well?
Explanation:
A first-person narrator is usually recounting an event, so they definitely use 'I'.
A third-person narrator sometimes knows the thoughts of other characters, depending on whether they're omniscient or not.
A first-person narrator is likely to show bias I think, because they're telling the story from their point of view so they're very likely to share their opinions and stuff. I don't really know, you're gonna kinda have to decide on this one.
A third-person narrator sometimes takes part? I mean, if they're third-person limited then usually it's the POV of a character but from a more detached persona? For example, in the Heroes of Olympus series all the chapters are in third person limited but all the characters take part in the action. If it's third-person omniscient then I don't think they'd be taking part in the action, unless the narrator is like a dude from the future recounting events that happened to his younger self and all that stuff. I don't really know, man.
