Personification gives human-like characteristics to non-human things. The air doesn't have lungs therefore it can't "breathe". The personification here is simply that the air is being described as breathing.
B is the answer for the question
Talk: if the word "did"(helping verb) is in front of the word it is meaning that someone spoke in the past, but if the helping verb "will" is before the word it means that someone is going to speak in the future (most likely about to start talking)
talk-"ing": the same thing as "talk" EXCEPT "ing" is a suffix which means presently, so "talking" means that someone is currently speaking.
talk-"ed": once again the same thing, however, the suffix "ed" means already DID or in the past.
talk- "en": actually this is sadly not an english word, but the suffix "en" means made of. For example, "golden" means MADE OF gold.
Hope this helped:)
