Answer: A. Rangeland → Pastureland
Rangeland can be defined as biome, which is dominated by the growth of shrubs and grasses. These are found in grassland, woodlands , wetlands, shrublands and deserts. A rangeland can be used as pasture land. A pasture land can be any land used for grazing by wild and domestic herbivorous animals. The rangeland can be appropriately used as pasture land because it provides a substratum for the growth of large diversity of grasses, hence, can be used as land for grazing domestic animals like cattle sheep, cow and buffalo. Therefore, reduces the expense of commercially available fodder.
