Ice Floats in Room Temperature Water, but Does It Float

Ice floats in room temperature water, but does it float in boiling water? Why or why not?

A) As liquid water heats up and boils, it will become less dense, therefore the ice will sink.
B) As water cools, it becomes more dense. When it freezes however, it becomes less dense as it forms ice crystals. Therefore, it will sink in boiling water, but float in water at room temperature.
C) It is impossible to have ice in boiling water.
D) If boiling water is less dense than ice, the ice cube should sink.
