Ice Melts Spontaneously at Room Temperature, Even Though the Process

Ice melts spontaneously at room temperature, even though the process is endothermic. How is this possible?

A) There is a large increase in entropy.
B) OH is small, so melting still obeys the second law of thermodynamics.
C) The Gibbs free- energy relationship does not apply to phase changes such as melting.
D) There is an increase in free energy when ice melts.
