Question
Can ice be melted merely by applying pressure? Please pick the best answer with the best explanation for that answer. [ ] Yes. Water expands when it freezes, so applying pressure actually decreases its melting point. [ ] Yes. Applying energy by squeezing raises the temperature of the ice and causes it to melt. [ ] No. Applying pressure prevents the molecules from escaping the crystal lattice. [ ] No. Applying pressure to a solid actually increased its melting point. [ ] It is not possible to say without further information. Can ice be melted merely by applying pressure? Please pick the best answer with the best explanation for that answer. [ ] Yes.

This can be well explained by the phase diagram of water.
The increase in pressure causes the water to expand and freeze. So if we are applying pressure then it is decreasing the freezing point (melting point) of water.
so answer is
Yes. Water expands when it freezes, so applying pressure actually decreases its melting point
