The answer to the 'Teresa's Daughter' riddle

This is the riddle that probably f**ked you up for a good 15 minutes, but if you figured it out 'easily' then you're a goddamn liar (or just smart, good on ya!).

Here's how you figure it out:

"My daughter's mother" means "me" but in different wording. If you replace "My daughter's mother" with "me," the sentence will read as "If Teresa's daughter is me, what am I to Teresa?" Therefore the answer is C, you are Teresa's Daughter.

You're welcome, now you can sleep at night.
