Choose the correct question tag for the sentence:

You haven't got a pen, _______?

have you?

The correct answer is Option (3) - have you?

• When the main part of the sentence is negative ("haven't got"), the question tag should be positive, which in this case is "have you?"

OTHER OPTIONS

• "do you?" → Incorrect, as it doesn't correspond to the verb form in the sentence.
• "don't you?" → Incorrect, as it would require a positive main clause.
• "isn't it?" → Incorrect, as it does not relate to the verb used in the main clause.
