A
precipitate
B
ice
C
water
D
water vapor
Explanation: 

Detailed explanation-1: -In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension.

Detailed explanation-2: -Precipitation can happen for various reasons, such as that you cooled a solution, or removed some solvent by evaporation, or both. (This is often used as a way to purify a compound.)

Detailed explanation-3: -Chemical precipitation is the process of conversion of a solution into solid by converting the substance into insoluble form or by making the solution a super saturated one.

Detailed explanation-4: -A saturated solution is one containing as much solute-the solid being dissolved in the liquid-as possible without forming a precipitate, or leftover solid.
