Ice water and salt. The salt lowers the freezing point of the mixture below that of pure water with ice.

Ice water and salt. Ice is 32 degrees F. Salted ice water can be much lower.

Salty water freezes at a lower temperature than plain water. But the ice is made of plain water, so it melts at 0 degrees Celsius. Since the ice keeps melting, but the water no longer freezes (because there is only salt water, which doesn't freeze at 0 degrees), the temperature goes down.

I believe Ice would be coldest because it is not being warmed by water or other sources. Ice in water, is being warmed becuase of the water will not be as cold as the ice. And Ice and salt have a bad chemical reaction which I don't suggest you try.

The lowest temperature ice AND water can achieve is 0C. Slightly less if you start fiddling with pressure, but not much.
The lowest temperature ice, water and salt can achieve is about -15C - again, slightly less if you start messing with other factors.
But the lowest temperature ice ALONE can achieve is absolute zero (about -273C). So, the answer is most likely ice.
The reason I have to say most likely ice is because ice can be as warm as 0C, so it could be colder than ice, water and salt.

Salt lowers the temperate at which water freezes so Ice water, and salt would be the coldest.

i would have to say ice and water bc the ice gets the water all around cold so i think its colder

salt speeds up the release of energy from the ice thats how you can make home made ice cream
