Answer :
personification is giving human characteristics to something non-human so the answer is A because leaves can't dance :)
The answer is A because its giving the object an action. For example, the stars danced playfully in the moonlit sky. Its giving the object an action that it wouldn;t normally do. Personification is when you assign the qualities of a person to something that isn't human or, in some cases, to something that isn't even alive
