The correct answer is option (C) The animal life in region B is more diverse than the animal life in region A.

Grasslands are the regions of vegetation dominated by grass, wild plants and herbs. Wetlands are the biologically diverse ecosystems with lands consisting of marshes and swamps.

Region A with grasslands alone, will mainly have animals which are herbivores and birds. Whereas, region B with grasslands, wetlands and mountains show a variety of animals or diversity of animals. This region has a number of herbivores and birds due to the presence of grasslands. Wetlands are of four types namely the swamp, marsh, bog and fen showing characteristic vegetation of aquatic animals, amphibians due to the presence of watery wetlands. They also show reptiles like alligators and crocodiles, birds like waterfowl, wading birds, mammals like bats, rabbits, thousands of invertebrates nd insects. Mountains are also a habitat for a large number of animals like mammals to insects. They serve as a place for the prey animals to escape from their predators.

Thus, a region with grassland, wetland and mountain will have a diversity of animals.

The answer is C. All of these different environments require a wider variety of adaptations.
