'Haven't you' is the correct tag. Question tags use the same auxiliary as the real question. e g. Do you like music? - You like music, don't you? Can you drive? - You can drive, can't you? Have you got brothers and sisters? - You've got brothers and sisters, haven't you?

B would be the correct tag question :)

Have got / question form is "Have you got?or tag question"haven't you?" To have /question form is "Do you have? Or tag question"don't you?"

Hi Fatima 🙂 B is the correct answer. You can make the sentence negative to find the auxiliary verb. Good luck 🤞
