Peter broke a jug, ________.
Choose the correct question tag from the following alternatives to fill in the blank:

The correct answer is Option A (didn't he?).

Key Points:
• This question tests the formation of question tags.
• Rules for Question Tags:
• 1. If the main sentence is affirmative, the tag must be negative. (Here, 'broke' is affirmative, so the tag will be negative).
• 2. If the main verb is in the simple past tense ('broke' = V2), the auxiliary verb used in the tag is did.
• 3. The subject must be a pronoun corresponding to the subject of the sentence ('Peter' becomes he).
• Constructing the tag:
• Statement: Peter broke a jug (Simple Past, Affirmative).
• Auxiliary + Negative + Pronoun = didn't he?
• Key Takeaway: For an affirmative past tense sentence ('broke'), use the negative auxiliary 'didn't' and the pronoun 'he'.
