Answer: A. Lower the freezing point.

Explanation: There are two ways the lowering of freezing point happens at higher pressures. From the densities it's quite obvious we're speaking of ice (0.9g/cm³) and water (1g/cm³).

Ice occupies more volume than liquid water, therefore increasing the pressure favours the liquid state over the ice state. Also at higher pressure, more air, which is a mixture of gasesgoes into solution. The more molecules of air dissolved in the water, the lower the freezing point.

It is worthy to note that water has a unique characteristic. Water unlike other substances gets a reduction in freezing point whereas others' freezing points increases ever so slightly.
