Answer

Brief Explanations:

In an open - system, matter can be exchanged with the surroundings. Initially, there is 12 grams of ice. Option E shows a total mass of 12 grams (8 grams liquid water + 4 grams water vapor), but the presence of water vapor indicates that some of the water has escaped into the surroundings as a gas, which is characteristic of an open - system.

Answer:

E. The container contains 8 grams of liquid water and 4 grams of water vapor.
