Which one of the following is used as an anti-freeze for the automobile engines?

1. An anti-freeze is a substance added to water, typically in the cooling systems of automobile engines, to lower the freezing point of the mixture and prevent it from freezing in cold temperatures. 2. Ethylene glycol is the most common chemical used as the base for automotive anti-freeze and coolant. 3. It possesses properties that effectively lower the freezing point and also raise the boiling point of water, providing protection in both cold and hot conditions. 4. While alcohols like methanol and ethanol can also act as antifreeze agents, ethylene glycol is generally preferred for automotive applications due to its overall performance characteristics, including a higher boiling point and better heat transfer properties. Propyl alcohol is not typically used for this purpose.
