Hello there!
"I was a shipwreck as I was getting ready for that presentation."
Correct answer C: metaphor.
A Metaphor is a figure of speech that makes an implicit or implied comparison between two things that are unrelated, but which share some common characteristics because of it's meaning.
In this case, shipwreck is a noun, and it means the sinking of a ship; failure and destruction. Someone can not be literally a shipwreck, but, metaphorically, it means they can be a failure. :)
Hope this helps.
