Answer:
The correct answer is option c. "At higher elevations, it would take less time to hard boil an egg, because there is a lower boiling point. Therefore it would take less time to achieve the boiling point".
Explanation:
The elevation has a inversely related effect on the boiling point of water. For instance, water boils at 100 °C at sea level, but it is reduced to 93.4 °C at 1,905 meters of altitude. At higher elevations, it would take less time to hard boil an egg, because there is a lower boiling point. Therefore it would take less time to achieve the boiling point, and the water would boil faster than it does at sea level.
