Question tags – present perfect negative: supply the correct tag for "You haven’t had your lunch yet, ____ you?" Sentence: "You haven’t had your lunch yet, ____ you?" Choose the auxiliary and polarity that form the correct tag.

Given data

• Main clause: present perfect negative "haven’t had".
• We must form a tag with opposite polarity and matching auxiliary.

Concept/Approach
Question tags invert the polarity: negative main clause → positive tag. The auxiliary in the tag must match the main clause's auxiliary: here, have.

Step-by-step logic
Main clause: "You haven’t had …"Auxiliary = have; Subject = you; Polarity for tag = positive → "have you?"

Option analysis
have — correct: "… haven’t …, have you?" ✅haven’t — wrong polarity; would match a positive main clause.are / aren’t — wrong auxiliary (be), not used with present perfect in this sentence.

Common pitfalls

• Repeating the negative in the tag after a negative main clause.
• Using be instead of the correct auxiliary have for perfect aspect.

Final Answer
have
