Monty fully filled a glass bottle with water, put a stopper on it and placed it upright in the freezer overnight. When he looked at it in the morning, the stopper was out of the bottle and a column of ice had emerged through the opening of the bottle.
Which one of the following is the best explanation for what Monty had observed?

AThe bottle had contracted when it was put in the freezer and the water could no longer fit into it.
BExtra water condensed from the air in the freezer and then froze to form the column of ice.
CThe bottle and the stopper contracted more than the water, allowing it to pour out and form the ice column.
DThe volume of water had increased when the water froze, forcing the stopper out of the bottle and forming the column of ice.
