You are at the north pole where the temperature is minus 50 degrees C below freezing. What sort of thermometer would you use to measure it?
- Water.
- Alcohol.
- Mercury.
Explanation from PART66Online
Mercury freezes at about minus 39 degrees C, so it cannot measure minus 50 degrees C. Alcohol (spirit) thermometers stay liquid to roughly minus 115 degrees C, making alcohol the correct choice for very low temperatures. A water thermometer would freeze well before that point.

Because mercury freezes near minus 39 degrees C, at minus 50 it is solid in the bulb and cannot rise, answer is B. Alcohol stays liquid to roughly minus 115 degrees C, so spirit thermometers are the standard choice for very low temperature measurement.
