Answer: (B)

Verified step by step guidance

1. Understand the concept of vertical stratification: Vertical stratification refers to the layering of vegetation in a biome, which is most pronounced in areas with high biodiversity and complex ecosystems.
2. Identify the biome with the most pronounced vertical stratification: The tropical rainforest is known for its complex structure with multiple layers, including the emergent layer, canopy, understory, and forest floor, making it the biome with the most pronounced vertical stratification.
3. Understand the characteristics of the northern coniferous forest: Also known as the taiga, this biome is characterized by its cold climate and is the largest terrestrial biome on Earth, covering vast areas across North America, Europe, and Asia.
4. Match the characteristics to the correct biomes: The tropical rainforest is associated with pronounced vertical stratification, while the northern coniferous forest is recognized as the largest terrestrial biome.
5. Review the options and select the correct answer: Based on the understanding of the biomes, the correct answer is 'Tropical rainforest; largest.'
