During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this?
As the water contracts during freezing, the cells would pull away from each other causing damage.
Less water in the cells means the cells are smaller and need to do less work.
The expansion of excess water as it turns to ice inside the cells would break the cells apart.
The frozen water constricts organelles and causes plant cells to shrink.

Can't be A because water expands when it freezes. ;) I'd say you're right.

On another note though, I'd also say that it lowers the freezing point of the water inside the plant so that it doesn't freeze solid as easily. The more concentrated a solution is with particles in it, the lower the freezing and higher the boiling points.
