You Collect and Measure Samples of Ice and Surrounding Ice

You collect and measure samples of ice and surrounding ice water from a stream in the Winter.You find that you collected the same number of water molecules in each form.Water in the ice (solid) form floats in water of the liquid form because

A) in the ice form, the same number of water molecules are found in a crystal form, yet total larger volume than the liquid water.
B) in the ice form, the same number of water molecules are found in a solid, more compact volume than the liquid water.
C) once the water molecules froze into ice, they became hydrophobic, and started repelling from the liquid.
D) the ice is actively melting, since it was surrounded by the liquid water in the stream where it was collected.
