CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. The candle circle sits inside the lamp circle, and the lamp circle is separate from the chair circle. So no candle can be a chair: conclusion I follows.

  2. 'No' is reversible: 'No candle is a chair' says exactly the same as 'No chair is a candle'. Conclusion II follows too.

  3. Both I and II follow.

Concept
All + No gives No; No is reversible
