Choose the correct Question Tag: You went to the market yesterday, __…

The correct answer is Option (2) → didn't you

Question tags:

• Rule: a positive statement takes a negative tag, and a negative statement takes a positive tag.
• When the statement has no helping verb, the tag uses a form of do in the same tense:
  • Simple present: do / does.
  • Simple past: did.
• This sentence: "You went ..." is positive and in the simple past, with the subject you, so the tag is didn't you.

Complete sentence: You went to the market yesterday, didn't you?

Why the Other Options are Incorrect?

Option 1: did you — Incorrect. A positive statement needs a negative tag.

• "Is" does not go with "you".

Option 4: doesn't you — Incorrect.

• "Does" is present, but "went" is past.
• "Does" does not go with "you".
