Why Might One Find Tundra,glacier,and Polar Conditions at Low Latitudes

Why might one find tundra,glacier,and polar conditions at low latitudes?

A) The cooling effect of altitude can produce these features.
B) Cold ocean currents off the west coast of continents produce exceptionally cold conditions at low latitudes.
C) High albedo due to some land cover types prevent the absorption of insolation.
D) The high variability of day length and low sun angle create cold conditions at low latitude.
E) These are anthropogenic features that have resulted from deforestation and subsequent shifts in climate systems.
