* Ice is frozen water. Water has a melting point of 0°C (32°F) and a boiling point of 100°C (212°F). So, ice has a much lower boiling point than any of the other options.

* Alcohol (like ethanol) has a boiling point of 78.37°C (173.07°F).

* Water has a boiling point of 100°C (212°F).

* Oil has a much higher boiling point, typically ranging from 200°C to 300°C (392°F to 572°F) depending on the type of oil.

Therefore, ice has the lowest boiling point.
