Choose the sentence that uses the correct question tag:

The correct answer is Option (4) → Those mangoes are from Ratnagiri, aren’t they?

Question tag after “these / those”:

In the tag, “these” and “those” become “they”. The helping verb here is “are”. The sentence is positive, so the tag is negative: “aren’t they”.

Why the Other Options are Incorrect?

Option 1: The monsoon arrived early this year, hasn’t it? — Incorrect. The given sentence says “arrived ..., hasn’t it”. “Arrived” is a simple past verb with no helping verb, so the tag uses “did”, not “has”.
Corrected: The monsoon arrived early this year, didn’t it?

Option 2: Kunal is coming to the Ganpati pandal, is he? — Incorrect. The sentence is positive, but the tag is also positive. A positive sentence takes a negative tag.
Corrected: Kunal is coming to the Ganpati pandal, isn’t he?

Option 3: My sisters can speak Marathi well, can’t she? — Incorrect. The subject “my sisters” is plural, so the pronoun in the tag is “they”, not “she”.
Corrected: My sisters can speak Marathi well, can’t they?
