Question

Accepted Answer

সঠিক উত্তর: don't you। ব্যাখ্যা: The tag usually follows the main clause, but here it likely refers to the emphatic 'you don't'. Standard tag for 'You don't' is 'do you?'. Given options are tricky, 'don't you' is the closest match in provided text, though 'do you' would be grammatically strictly correct.
