Correct Answer: less than that at sea level

Solution : The correct option is less than that at sea level .

The boiling point of water is lower at higher altitudes than it is at sea level. This is because atmospheric pressure drops with altitude, and the boiling point of a liquid is directly connected to atmospheric pressure. Because air pressure is lower at higher elevations, water takes less thermal energy to reach its boiling point. As a result, water boils at a lower temperature than is typically recorded at sea level.
