Step 1: Recall the Rule of Tag-Questions
- A tag-question must agree with the subject of the sentence.
- If the main clause is positive, the tag must be negative; if the main clause is negative, the tag must be positive.
Step 2: Check Each Option
- Option 1: “He has few reasons..., has he?” → Correct, because “few” implies a negative sense, so the positive tag fits.
- Option 2: “You like to play, don’t you?” → Correct, positive statement + negative tag.
- Option 3: “There’s little point..., is there?” → Correct, “little” is negative in meaning, so positive tag works.
- Option 4: “He plays well, isn’t it?” → ❌ Wrong. Subject is “he,” so the tag must also match: “doesn’t he?” not “isn’t it?”
- Option 5: “Nobody has called..., have they?” → Correct, “nobody” is singular but takes plural tag “they” in English usage.
Step 3: Conclusion
The incorrect tag is in Option 4. The correct version should be: “He plays well, doesn’t he?”
Final Answer:
\[ \boxed{\text{Option (D): Moreover, he plays well, isn’t it?}} \]
