What type of wordplay is the following? "I'm trying to imagine you with a personality." A. Metaphor B. Paradox C. Pun D. Sarcasm A?

Sarcasm would be my answer.

A - Metaphor compares things - this isn't comparing a person to anything. It's more of an observation of a situation.

B - Paradox requires the argument to be sound, yet concludes in senseless. Without further information, we can't assume "you don't have a personality" to be a sound argument, because everyone has a personality.

C - Pun requires some type of word play, which this has none.

D - This is the most likely. We expect everyone to have a personality. Someone making a comment like this sentence is suggesting that the person does not, likely as an attempt at insulting their behavior as bland or boring.
