While going through a heap of junk in her garage, Jackie found an uncalibrated mercury thermometer. After a few experiments, she succeeded in calibrating it. Her notes show that the ice point of the thermometer corresponds to 3 cm while the steam point corresponds to 30 cm of mercury. If Jackies calculations are fine then length = 15 cm would correspond to

• A. 44 °C
• B. 46 °C
• C. 40 °C
• D. 42 °C
