Geological evidence points to a few very deep "snowball" phases in Earth's history, in which the oceans would have been mostly frozen. How did Earth recover from a snowball phase?

A) The increased ice coverage on Earth's surface absorbed more sunlight than water and rocks, thus gradually heating Earth until the ice melted. B) Life vanished, leading to an increase in CO2, and increased global warming, eventually melting the ice. C) Volcanoes continued to inject CO2 into Earth's atmosphere, increasing the greenhouse effect to the point where ice melted. D) Plate tectonics gradually subducted all the ice below Earth's surface. E) As the Sun aged, it grew brighter and increased Earth's temperature, melting the ice.
