In this question, we are comparing the boiling points of four different samples of water: distilled water, bottled mineral water, well water, and sea water. The question asks which sample of water will have the lowest boiling point compared to the other three samples.

Distilled water, option-1, is water that has been purified through a process of distillation, where impurities and minerals are removed. Distilled water is known for its low boiling point because it lacks any impurities or minerals that can raise the boiling point. Therefore, it is reasonable to expect that distilled water will have the lowest boiling point compared to the other three samples.

Bottled mineral water, option-2, is water that contains natural minerals and is typically sourced from underground aquifers. It may have a higher boiling point due to the presence of minerals.

Well water, option-3, is water that is sourced from a well and may contain various impurities and minerals depending on the location. Its boiling point could be higher than distilled water due to these impurities and minerals.

Sea water, option-4, is water from the ocean, and it is known to have a high boiling point due to the presence of salts and other dissolved substances.

Therefore, out of the four options, distilled water
