The correct answer is - A. slanted roofs.

People from the cold regions of Finland an Russia where there's lots of snow tend to make their houses with slanted roofs. Very often they try to make the angle of the slanted roofs as big as possible so the houses get kind of ''cartoony'' appearance. This is because of the huge amounts of snow, so the bigger the angle of the roof the less snow will be kept on it, but it's not just the shape that doesn't allow big amounts of snow on it, even if there's more snow accumulated on it because of the angle of the roof the snow from the top pushes towards the snow below it thus making the snow push itself down from the roof.
