Which example below is a metaphor?
1.Buzz! Buzz! The sound of the fly was enough to drive Juan crazy.
2.J.enna was the key that unlocked the door for Lena meeting new friends at her new school.
3."Peter Piper picked a pack of pickled peppers."
4.all of the above
Because number one is a onomatopoeia, the third one it an alliteration, so 4 can’t be it so it leaves us with 2. Which is basically saying that Jenna is like the key.
