Concept:A negative statement is usually followed by a positive question tag.
Explanation:The sentence says "The musicians have not arrived from Sierra Leone."
This statement is negative because it contains "have not."
The auxiliary verb is "have," and the subject is "they," referring to the musicians.
Since the statement is negative, the question tag must be positive.
So the correct tag is "have they?"
Therefore, the sentence becomes: "The musicians have not arrived from Sierra Leone, have they?"
This matches option D.
Answer:D. have they
