Choose the most natural response to finish the coworkers' Friday afternoon conversation.

Coworker: "See you Monday! Have a great weekend!"
You: "_____"

The correct answer is You too!

When someone wishes you a good weekend, a nice evening, or a great holiday, the most common and natural way to return the wish is by saying "You too!"

Saying "Me also" or "Yes, I have it" sounds very unnatural to native speakers. "You too" is a perfect, friendly fixed expression for this situation.
