The correct options are
A high temprature
D high pressure
The melting of ice is favored by high pressure and high temperature.
ice+heat⇌water
The melting of ice is an endothermic reaction.
At high temperature, the equilibrium shifts to the right so that the heat absorbed lowers the effect of increased temperature.
This is according to Le chatelier's principle.
The density of water is higher than the density of ice at freezing temperature.
Hence, volume of ice is higher than the volume of water at freezing temperature.
Hence, the melting of ice is accompanied by decrease in the volume.
Hence, it is favored by high pressure.
