A)   methane (CH4), ammonia (NH3), and water (H2O) ices, whose relative abundances vary with the seasons.
B)   carbon dioxide (CO2) ice, which evaporates easily, overlaying thicker and more long-lived water (H2O) ice.
C)   only carbon dioxide (CO2) ice, which is very volatile and melts easily.
D)   only water (H2O) ice, which does not melt easily and survives the summer heat.
