Final answer:
The mass of ice formed from water will be equal to the mass of the original water, in accordance with the law of conservation of mass. So the correct answer is Option B.
Step-by-step explanation:
According to the law of conservation of mass, the mass of ice made from a certain mass of water would be equal to that of the water. This law states that mass is neither created nor destroyed in a chemical reaction, which includes phase changes like freezing. Therefore, if we start with a certain mass of water and freeze it to turn it into ice, the mass of the ice will be the same as the mass of the water we started with, despite any change in volume or density due to the phase change.
