I would choose the last choice, D. Adverbial.
Adverbial phrases include two or more words that serve as adverbs. So "in an hour or two" can be classified as an adverb phrase.
A four letter word? my guess would be <em>LEAP</em>
It does not have a specific rhyme scheme.It has a free form.It does not have a set meter.
First-person point of view. If it was written in third person limited then you would only get the thoughts and feelings of only one character in the story,but if it was written in third person omniscient, then you would see the thoughts and feelings of another character. After that it goes to third person omniscient you may know things that other characters may not know yet.
