Personification gives human traits to non-human objects. I will first prove that the other answers are false, and then provide an example for personification.
A metaphor is comparing two unlike objects. For example, "a sea of grief."
A sea does not have grief, but is comparing the two.
Symbolism is having an object or idea having a much deeper meaning than it is.
Imagery is providing description of the 5 senses for a scenario. For example, "The smell of the oranges."
Personification is giving non-human objects human traits. For example,
"The wind whispered in my ear."
Personification is your answer, I hope this helps!
