The correct answer is option 2: Podsols.

Tundra soils, mentioned in option 1, are associated with the arctic tundra biome, which is characterized by permafrost and a lack of trees. Asha-grey soils, on the other hand, are found in high-latitude coniferous forests.

Grey-Brown soils, mentioned in option 3, are a type of soil found in temperate regions, typically characterized by a moderate amount of organic matter. This does not match the description of asha-grey soils.

Red and Yellow soils, mentioned in option 4, are common in tropical and subtropical regions, with a high content of iron oxide, giving them their characteristic color. Again, this does not match the description of asha-grey soils.

Therefore, the most accurate option is option 2: Podsols. Podsols are soils found in coniferous forest regions of high latitudes, characterized by a layer of organic matter on the surface and a distinctive leaching of minerals due to the acidic conditions.
