Question

Add a question tag:

I lost my key, _______?

• A. haven't I
• B. have I
• C. didn't I
• D. don't I

Answer 1

Answer: (C)

didn't I

Question tags are used in a sense that contradicts the rest of the sentence. Moreover, the verb remains the same without any change in tense. Since the rest of the sentence is in positive, the question tag should be negative. Hence, Option B is correct. The rest of the options either have the same sense as the sentence or use a different verb. Hence, these are incorrect.
