$A$ Carnot engine absorbs $1000\,J$ of heat energy from a reservoir at $127\,^oC$ and rejects $600\,J$ of heat energy during each cycle. The efficiency of the engine and the temperature of the sink will be:
- A$20\%$ and $-43\,^oC$
- B$40\%$ and $-33\,^oC$
- C$50\%$ and $-20\,^oC$
- D$70\%$ and $-10\,^oC$
