If the boiling point of water in Delhi is 100° C, then what will be the temperature of water in Mussoorie?
The boiling point of water decreases with increasing altitude. Mussoorie is at a higher altitude than Delhi. Therefore, the boiling point of water in Mussoorie will be less than 100°C.

The correct answer is option B. The boiling point of water decreases with increasing altitude due to the reduction in atmospheric pressure. Mussoorie is at a higher altitude than Delhi, which means it experiences lower atmospheric pressure. This lower pressure reduces the boiling point of water in Mussoorie compared to Delhi. Therefore, the temperature of water in Mussoorie would be less than 100°C.
Options A, C, and D are all false. Option A suggests that the temperature in Mussoorie would remain the same as in Delhi, which is incorrect due to the altitude difference. Option C implies that the temperature in Mussoorie would be higher than 100°C, which is not true as water boils at a lower temperature at higher altitudes. Option D states that all options are false, which is incorrect since option B is true; the temperature of water in Mussoorie would indeed be less than 100°C due to its higher altitude. Therefore, option B is the correct answer.
