physical chemestry -Physical Equilibrium - help :)?

A container is filled with ice in a pressure of 1 atm.
The container is in a bath that keep its Temperature constant - 273.15 K.
We cover the ice with a piston, and we press the piston with 100 atm.
We wait until the system reaches equilibrium.

Given is:
delta(fus)Hm = 6 [kj/mol]
dVm (ice->water) = -1.73 [cm^3/mol]

What is the process that will happen, when the pressure is applied on the piston (Choose only one):
a) Temperature will increase
b) Ice will melt
c) System will go back to equilibrium by decreasing its Temperature
d) Nothing will happen
e) Sublimation will occur
