According to the text, which statement accurately describes the relationship between leaf size and environmental conditions?

  • A: Pygmyweed (Crassula connata) has large leaves because it grows in dry, sandy regions.
  • B: The palm Raphia regalis has small leaves, adapted to its African rainforest habitat.
  • C: Large leaves are typically found in species from tropical rainforests, where water is abundant.
  • D: Small leaves are primarily found in aquatic plants to maximize light absorption underwater.

Explanation

The text states that 'The largest leaves are typically found in species from tropical rain forests, whereas the smallest are usually found in species from dry or very cold environments, where liquid water is scarce and evaporative loss is more problematic.' This clearly indicates that large leaves are associated with water-abundant environments like tropical rainforests.
