Option D is correct: Boreal forests, or taiga, represent the largest terrestrial biome. Occurring between 50ᵒ and 60ᵒ north latitudes, these can be found in the broad belt of Eurasia and North America. Boreal Forests are dominated by conifers, especially spruces and firs. These are dotted with lakes, bogs, and marshes. There is little rainfall in the boreal biome. Precipitation comes in the form of fog and snow, with a little rain during the summer months. There are long, service winters (up to six months with mean temperature below freezing) and short summers (50 to 100 frost-free days), as is a wide range of temperature between the lows of winter and highs of summer. The soils of the boreal forest are often acidic, due to falling pine needles, and low on nutrients since the cold temperature does not allow much foliage to rot and turn into dirt. Hence, statements 2 and 3 are correct.

Boreal forests: Characteristics and Distribution
The Boreal forests, also known as Taiga, are the world's largest terrestrial biome. They are mostly prevalent in high-latitude regions of the Northern Hemisphere, covering a vast area of around 16 million km². The following are the key characteristics of the Boreal forests:
1. Climate: The Boreal forests are characterized by long, cold winters and short, mild summers. The temperature range between the lows of winter and highs of summer is wide, ranging from -50°C to 20°C.
2. Precipitation: The Boreal forests receive moderate to heavy snowfall in the winter and moderate rainfall in the summer. The annual precipitation ranges between 400-900 mm.
3. Soils: The soils of the Boreal forests are often acidic with low nutrient content. The low temperatures and slow decomposition rates result in the accumulation of organic matter on the forest floor, creating a thick layer of acidic humus.
4. Vegetation: The Boreal forests are dominated by coniferous trees, such as spruce, fir, pine, and larch. The forest floor is covered with mosses, lichens, and low shrubs.
5. Fauna: The Boreal forests support a diverse range of animal species, including large mammals such as moose, caribou, and brown bears, as well as smaller animals such as beavers, lynx, and wolves.
Conclusion
From the above discussion, it is clear that the statements 2 and 3 are correct, while statement 1 is incorrect. The Boreal forests are not confined to permafrost regions, although they do occur in regions with cold climates and heavy snowfall. The acidic soils and wide temperature range are characteristic features of the Boreal forests.
